Some diagrams can get very large and complex, for example, business processes, UML diagrams, floor plans, or even large brainstorm mind maps and hierarchical tree diagrams. These diagrams are often more readable when they are broken into smaller component diagrams.
As draw.io aims to become the de facto diagramming tool, used by everyone around the world, it's important to be able to import from a variety of file formats and from a number of storage locations.
Lucidchart recently limited their free education plans, Lucidchart EDU, for students and teachers to only 3 editable diagrams. That means that all of the diagrams after your most recent three diagram files are set to read only, unless you switch to a premium subscription.
Run your own diagramming server using our Docker image of draw.io. This image includes server-side support for export to PDF, image and .vsdx formats, diagram storage with Google Drive and OneDrive, without any dependency on the draw.io servers.
