Mermaid Chart is my go to for creating diagrams! By removing the design and layout steps, Mermaid Chart simplifies the diagram creation process and allows me to build diagrams in less than half the time of alternate tools!
An amazingly good and simple product. I use it all the time at work to create Sequence Diagrams to align with customers and internally with the tech team.
It's like writing pseudo code but with the added benefit of it creating visuals for you. Big fan!
I've found Mermaid to be a great tool for putting diagrams into GitHub - it only takes a few minutes to learn the syntax and the docs are really clear.
