Diagram types
There are ninety-odd diagram types on this branch, which sounds like a lot until you notice that most people need four of them. The grouping below is by the question you are answering rather than by the tool you would use, because the tool is the easy part.
If you already know what you want to draw, use the sections below. If you know which editor you prefer, Guides is organised that way instead.
#If you are not sure where to start

You want to show | Start with |
|---|---|
How work moves through steps | Flowcharts and processes |
How a system is put together | Software and architecture |
What the data looks like | Data and databases |
Where things are deployed or connected | Cloud and deployment, or Infrastructure and network |
When things happen | Planning and project |
What the numbers say | Charts and data visualization |
Every type here is editable after the fact. Nothing you draw is flattened into an image, so the diagram on a page three years old can still be opened and changed.

Ninety types. You will use four of them, and that is fine.
