Ask HN: What diagrams do you use in software development?

1

Graphviz

I mainly use diagrams in documentation and not in specification or development (although tools I am learning to use, such as Alloy [0], for specifications do generate diagrams of the state). In documentation I typically use a mix of ditaa[1], mermaid[2], and graphviz[3]. I used ditaa for architecture diagrams, a mix of sequence, flow chart, and ER diagrams in mermaid to explain protocols or interactions; and I use graphviz usually for datastructures or dependencies, etc. [0] https://alloytools.org [1] https://ditaa.sourceforge.net [2] https://mermaid-js.github.io/mermaid/#/ [3] https://graphviz.org/.

Excalidraw

Flow chart, sequence and class diagrams are the ones I use the most in my current job. In source, I generally use Mermaid[1] as its syntax is easily maintainable and understandable. As our documentation (mdBook) is written in markdown and can render Mermaid via a plugin[2]. When drawing quick diagrams during online communications, I use Excalidraw[3] as it's easy to use and has a nice whiteboard style to it. When I'm with my team (pre-covid), whiteboard or paper did the trick. [1]: https://mermaid-js.github.io/ [2]: https://github.com/badboy/mdbook-mermaid [3]: https://excalidraw.com/.

Https://diagrams.mingrammer.com/ I hate Visio so much, I do not hate any other software that much.

Diagrams.net

Draw.io is amazing! It has now been renamed to diagrams.net: https://app.diagrams.net/ Github repo: https://github.com/jgraph/drawio It's very easy to self-host, especially on Github Pages: https://github.com/jgraph/drawio#running There's also desktop apps for Windows, GNU/Linux, Mac and Chrome OS: https://github.com/jgraph/drawio-desktop/releases/latest.

GoJS

I actually make a diagramming library for the web, called GoJS: https://gojs.net So I make all kinds of diagrams, mostly as demonstrations. When developing an API itself, especially one where there are phases (objects must measure themselves and draw in a certain order, and not more than they need to), state machine-style and flowchart-style diagrams are awfully helpful.

Terrastruct

I've recently started using Terrastruct, which I've come to enjoy as I feel like I can quickly put together business logic and share it with the team without the tool getting in the way: https://terrastruct.com/.

Markdeep

Markdeep[0] from Casual Effects has a way of drawing diagrams using extended markdown. I used it to write this document with two diagrams: https://loan-free-ed.neocities.org Other tool I like are PlanetUML[1], BoUML[2] and Modellio[3](it is very heavy though on system resources!)

js-sequence-diagrams

We use a lot of sequence diagrams. So much so that thanks to https://bramp.github.io/js-sequence-diagrams/ I've got a Netlify-powered static site for creating them interactively at https://sequence-diagrams.netlify.app/ using their JavaScript library.

For quick sketches of architectures, try https://isoflow.io (a tool I'm building). It's designed with a strong visual language in mind.
