Mermaid
Mermaid is a free tool that creates diagrams, charts and flowcharts from simple typed text instead of drag-and-drop. It is aimed at software developers and documentation writers, and its live editor lets non-programmers make diagrams too.
How hard it is to start using it. Easy: install it like a normal app, or use it in your browser. Advanced: you run it on your own server, use the command line, or it is a tool for developers.
