There are many shapes in the draw.io shape libraries that use more than one line or fill colour. These shapes are being updated so you can change each of the colours and style your diagram with more flexibility.

As the collection of shape libraries is rather large in draw.io, it will take some time to update all of those that contain multi-coloured shapes. The first two libraries that have been updated are Mockups and the AWS 3D shapes.

Each shape still contains a Fill and a Line (outline) colour that typically forms the background colour and the outer line colour of the shape. The additional colours are defined with new, customisable style settings.

For example, the Mockup Map shape has a white background and black outline, but also internal areas with different fill colours and a different internal outline colour.

The list of fill and outline colours will be different for each shape.

How it works

A default attribute was introduced for the fillcolor and strokecolor attributes.

Each shape has a list of defaultFillColors and defaultStrokeColors attributes which are used to show the customisable colours in multi-colour shapes. These are comma-separated lists that define the default colours in the fillColorStyles and strokeColorStyles attributes within a shape.

Right click on a shape, then edit the colour style attributes, then click Apply.

Which libraries have been updated?

The updated AWS 3D and Mockups shape libraries are available now in the current version of the web-based draw.io editor. The Cloud and IT shape libraries are in the process of being updated to this new, more flexible system of colours. Multi-colour shapes in other shape libraries will be updated after the IT shapes are finished.

Go to app.diagrams.net/clear.html to ensure you are using the most recent version of the online draw.io editor.

Gradients with multi-coloured shapes​

The gradient option in the Style tab of the format panel will use the main background fill colour. The gradient does not apply to any of the other additional colour styles within the multi-colour shape.

Reset to the original colour styles​

To revert to the original colour, the easiest is to copy the original style from an unstyled shape and apply it to the customised shape.

1. Select the unstyled shape. In the Style tab, click Copy Style.
2. Select the customised shape. In the Style tab, click Paste Style.

In addition to updating the main AWS and Azure shape libraries in draw.io, several new networking and cloud shape libraries have been added, including shapes for Alibaba Cloud, Dynamics365 and OpenStack.

Open cloud infrastructure shape libraries​

1. Click on More Shapes at the bottom of the shapes panel on the left.
   
2. Scroll down to the Networking section and enable the shape libraries you want to use.
   
3. Click Apply to open them in the shapes panel next to the drawing canvas.

Tip: Alternatively, you can always search for a shape if you know its name. For example, searching for "AWS beanstalk" will show all the shapes from the various AWS libraries that have both "AWS" and "beanstalk" in their shape names, even if you don't have the AWS shape libraries open. Hover over any of the shapes to see a larger preview.

Azure Power Platform and Dynamics 365​

The Power Platform shapes have been added to the Azure shape library. These components are often combined with Dynamics365 services and applications in cloud infrastructures.

Tip:* If you prefer to diagram in dark mode, the Azure and Dynamics365 shapes and their labels will automatically change colours to remain readable when you switch between dark and light modes.

OpenStack shapes= library​

OpenStack services and apps are common components of Citrix, GCP, IBM and other large hybrid cloud infrastructures. To clearly indicate which components are provided by OpenStack in your infrastructure diagrams, enable the OpenStack shape library.

Alibaba Cloud shape library​

Enable the Alibaba Cloud shape library to document your infrastructure in Alibaba Cloud platform. These shapes cover a wide range of apps and services.

Most of the infrastructure shapes don't have labels by default, as designers tend to rely on logo-recognition for their infrastructure components.

To make your diagram more accessible, select a shape and start typing to add a label. In the Text tab of the format panel, select the Bottom position, and update the Font Colour to match the colour of the Alibaba shape so it is consistent.

Tip: Format one shape and click on Copy Style in the Style tab of the format panel. Then, right-click on the canvas and choose Select Vertices, deselect any regions you may have added, and then click on Paste Style in the Style tab to copy the style onto all of the selected shapes.

Other cloud platform shape libraries in draw.io include Salesforce, Citrix, Google GCP, Amazon AWS, IBM, and more.

Export AWS diagrams generated from your actual deployed infrastructure to the .drawio format from Cloudockit and Cloudcraft.

The new IBM Cloud shape library in draw.io (right) reflects IBM's updated design language, and extends the existing IBM shape library (left) with a wide range of additional groups, connectors and infrastructure components.

IBM has provided their updated shapes for the new IBM Cloud shape library in draw.io. Please refer to their documentation for their design language style guide, where they explain how shapes and icons should be used in a wide variety of technical diagrams.

Enable the IBM shape libraries in draw.io

1. Click on More Shapes at the bottom of the shapes panel in draw.io.
2. Enable the checkbox next to the SAP shape library in the Networking section and click Apply.
   

Tip: There are also several IBM infrastructures in the template library. Select Arrange > Insert > Template from the menu or + > Template in the toolbar, and look in the Cloud > IBM category.

Using old and new IBM shapes in one diagram​

The new IBM Cloud shapes are compound shapes - a coloured background shape and an icon on top in the centre. This gives you more flexibility in styling your diagram as you can change the two shapes' fill colours independently.

The older shapes are round with a white icon and blue text label, while the new IBM Cloud shapes are square with a white icon and text (in light mode) or black icon and text (in dark mode).

There is also a larger and more varied set of groups (region shapes) in the new IBM Cloud shape library.

The example above is one of the IBM templates available in draw.io with the new IBM Cloud shapes replacing some older components.

Both sets of shapes work well when diagramming in dark mode - the new shapes will switch icon and label colours automatically to remain readable.

Tip: To make the labels look the same on all of your IBM and IBM Cloud shapes, you'll need to edit the text labels to ensure their case matches and the Font Color in the Text tab of the format panel.

However, mixing shapes from the two shape libraries and using their default label styles shows which components of your infrastructure are more recent at a glance, such as for IBM's newer cloud and Watson AI services.

Make your own IBM shapes​

The shapes in both the IBM and IBM Cloud shape libraries represent only part of the constantly expanding IBM Design Language.

You can easily make your own IBM shapes in draw.io using the black IBM .svg icons.

1. Add one of the IBM Cloud shapes that matches the colour you want to use to the drawing canvas to serve as a template for your new shape.
2. Add a simple rectangle from the General shape library.
3. Select the IBM Cloud shape on the drawing canvas and select then select Copy Size in the Arrange tab of the format panel. Select the rectangle and click on Paste Size.
4. Select the IBM Cloud shape again, then select Copy Style in the Style tab of the format panel. Select the rectangle again and click on Paste Style.
   
5. You may need to deselect the Line checkbox in the Style tab, but your shape background should now look correct.
6. Add a label, and move its Position to the Bottom via the Text tab of the format panel.
7. Now, make the compound icon. Drag the .svg file of the UI icon from the UI Icons list in the IBM Design Language - either from the webpage directly, or from your device - onto the drawing canvas to import it. Then drag it over the centre of the background square.
8. Finally, drag a selection box around the new compound shape, right click and select Group from the context menu.
   

Tip: To use this new shape in multiple diagrams, drag the group onto the Scratchpad in the shapes panel.

You can also save the Scratchpad with your custom shapes to share them with your colleagues.

1. Click on the pencil to the right of the Scratchpad library.
   
2. Select Export to save all the shapes in the Scratchpad to a custom shape library.
   
3. Enter a filename, select where to save the custom shape library file and click OK.

Mermaid is a text-based syntax that you can use to describe a diagram, and automatically lay it out neatly on the diagram canvas. Enter your Mermaid diagram description in draw.io via Arrange > Insert > Mermaid in the draw.io menu or + > Mermaid from the toolbar. draw.io has updated to Mermaid version 10.9.1 to support the new ELK automatic layout.

Text to diagram tools in draw.io​

There are several text-to-diagram tools built into draw.io:

• Mermaid diagrams
• SQL to entity shapes
• Specially formatted CSV data
• Basic text-to-diagram converter for trees and lists.

Example Gantt chart generated from Mermaid syntax

Some of these text-to-diagram features generate a diagram as an image on the drawing canvas, and some use draw.io shapes to automatically layout your diagram and let you continue adding draw.io shapes and connectors to it.

You can choose your preferred output when you generate a diagram from Mermaid syntax, although some diagram types - like the Gantt chart above - will only generate to an image.

Insert a Mermaid diagram in draw.io​

An example coffee machine debugging flow is described in Mermaid syntax below.

graph TD
   A(Coffee machine <br />not working) --> B{Machine has power?}
   B -->|No| H(Plug in and turn on)
   B -->|Yes| C{Out of beans or water?} -->|Yes| G(Refill beans and water)
   C -->|No| D{Filter warning?} -->|Yes| I(Replace or clean filter)
   D -->|No| F(Send for repair)

Add this Mermaid diagram to draw.io.

1. Select Arrange > Insert > Mermaid from the menu or + > Mermaid from the toolbar if you are using the Simple mode or the Sketch editor theme.
   
2. Enter the text description of your diagram using Mermaid syntax in the large text box.
3. From the drop-down list, select whether you want to insert the diagram with draw.io shapes (Diagram), or as a single image (Image), and click Insert.
   

Diagram (default): When you insert the Mermaid diagram using the draw.io shapes, you can connect additional shapes and connectors and style your diagram. To change the original Mermaid syntax, first delete the previously inserted shapes, and re-enter the Mermaid description of your diagram by repeating the steps above.

Image: To generate the Mermaid diagram as a single SVG image on the drawing canvas instead, select Image from the drop-down list before you Insert. If you hover over the SVG image, the Mermaid syntax is visible in the tooltip. Note that you can't edit or style the individual shapes or connectors in this SVG image version.

To change a Mermaid diagram added as an image, double click on the SVG on the drawing canvas and edit the Mermaid syntax to regenerate the image.

Please refer to the Mermaid documentation for the complete syntax and styling options.

New ELK layouts for large flowcharts​

The new ELK layout option, introduced in Mermaid version 9.4, can generate compacter versions of large and complex flowcharts.

Add the following renderer directive to the top your Mermaid diagram text description:

%%{init: {"flowchart": {"defaultRenderer": "elk"}} }%%

For example, to layout the example Mermaid graph shown above with the ELK renderer command, the insert Mermaid dialog looks as follows.

Click Insert, and the Mermaid diagram will be generated ad drawn with draw.io shapes.

While this example is small and simple, larger flows with complex decisions and many branches may be displayed better using this ELK renderer option.

Note: As this is an experimental feature from the Mermaid developers, it currently only supports the flowchart layout.

Large Mermaid flowchart with and without ELK

Below, one of the more complex draw.io flowchart templates has described in text using Mermaid syntax and inserted as an image. The more compact version on the left used the new ELK renderer directive, and the one on the right did not.

With the ELK renderer directive, the Mermaid code for this flowchart looks as follows.

%%{init: {"flowchart": {"defaultRenderer": "elk"}} }%%

draw.io will be available as an integration in the web-based GitLab Wiki editor on 22 March with the GitLab 15.10 release and product kickoff. When you add your diagram to a GitLab Wiki page while editing the source of that page, it will be saved as an SVG image containing the diagram code, and displayed in the page content.

Like all files in GitLab, the image with its embedded diagram is versioned, so all changes are tracked.

Note: As this integration is still under development until release, small changes may be made.

Diagram in the GitLab Wiki editor​

Add a new diagram: Click on Insert or edit diagram in the toolbar in the Markdown editor.

A blank diagram will be opened in the Sketch whiteboard-style editor theme. Use the diagramming toolbar on the left to access templates and shape libraries.

Save your diagram: It will be added to the page in Markdown as a .drawio.svg file.

Edit an existing diagram: Make sure your cursor is in the diagram file entry in the Markdown code, and select Insert or edit diagram.

View a diagram in the page: Click on Preview to render the page containing the diagram.

Diagram with the GitLab rich text editor​

Edit a diagram: Select the diagram, and click on Edit diagram in the hover toolbar that appears above or below.

Add a new diagram: Make sure no other diagram is selected, then click on the + in the toolbar and select Create or edit diagram.

Save individual diagram files to GitLab​

You can also store your individual diagram files in GitLab. Select GitLab as the save file destination when you create a new diagram, or select Save as from the menu.

Alternatively go to our online editor to start diagramming now using GitLab to store your diagrams.

You'll need to authorise access to your GitLab repositories, if you haven't already done so.

Tip:i As draw.io uses secure direct client authorisation, your password is never shared.

Diagram in VSCode with GitLab​

1. Set up the GitLab Workflow extension for Visual Studio Code.
2. Install Henning Dieterichs' unofficial draw.io extension for Visual Studio Code

The draw.io extension for VSCode lets you view and edit the .drawio diagram files stored in your repositories.

See how this extension works in GitHub - it works in a similar way with GitLab inside VSCode.

Note: The extension only recognises files with the .drawio file extension.

You can create network diagrams from scratch in draw.io using shapes that match the platform you are using - AWS, GCP, Veeam, Azure, Cisco, IBM and many more. Both the draw.io AWS19 and GCP Icon shape libraries for network and cloud architectures have been updated recently.

Open the updated network shape libraries​

Both the Amazon Web Service and Google Cloud Platform shape libraries have been updated recently. Enable the shape libraries that you need to use in draw.io.

1. Click on More Shapes in the left-hand panel.
2. In the Networking section, click on the checkboxes next to the libraries you want to enable, then click Apply.
   

If you want to see the shape names even when you aren't hovering over a shape in the shape libraries, click on the Labels checkbox in the shape library selection dialog.

Hover over any shape in the shape libraries on the left of the drawing canvas to see a preview and its name.

Drag the shape library panel edge towards the drawing canvas to expand the panel and see more shapes.

The Unified Modeling Language (UML) is a set of standard symbols and diagram types, commonly used in data modelling, workflow visualisation, and system modelling. UML notation is the defacto industry standard in the fields of software development, IT infrastructure, business systems and other fields. Many languages, such as SysML, SoaML, and a number of architecture frameworks use and extend UML.

The UML 2.5 specification updated the notation, or the shapes used in diagrams so they could represent a wider range of concepts more clearly. The specification document was extensively rewritten to make it easier to understand.

No new diagram types were added in UML 2.5 - the 14 diagram types that were previously defined in UML 2.0 are extended to cover the additional concepts, with many examples provided in the specification document.

UML diagram types​

UML diagrams are divided into two categories that provide you with static (structural) and dynamic (behavioural) views of a system.

• Structure diagrams: Class diagrams, component diagrams, composite structure diagrams, deployment diagrams, object diagrams, package diagrams, and profile diagrams.
• Behaviour diagrams: Activity diagrams, use case diagrams, state machine diagrams, and the four types of interaction diagrams - sequence diagrams, communication (collaboration) diagrams, interaction overview diagrams and timing diagrams.

Open this in our free diagram viewer

Enable the UML 2.5 shape library​

1. Click on More Shapes at the bottom of the left panel in draw.io, scroll down and click on the checkbox next to the UML 2.5 shape library in the Software section. You may want to also enable the UML shape library. Then click Apply.
   
2. The UML 2.5 shape library will appear in the left panel.
   

Using these shapes, and some of the shapes from the General and older UML shape libraries, you can create the full range of UML diagrams.

Example UML diagrams​

Click on a diagram below to open in our diagram viewer

Component diagrams show the dependencies between the logical and physical components of a system with the interfaces that each component requires and provides and their ports.

Composite structure diagrams are used to show the internal structure of a classifier, with its properties, parts and relationships, or how a collaboration behaves. You can break down the behaviour of a collaboration into one or more specific situations (occurrences) in a collaboration or collaboration use diagram.

Deployment diagrams shows the system infrastructure and how various software executables and artifacts are deployed on deployment targets.

Activity diagrams are used to model workflows in various ways. In this example, the workflow actions are arranged into swimlanes representing the actors, with a section that allows an interrupt (exception) to cancel the order.
