Ask HN: What do you use to create diagrams?
I'm clearly biased since I work at Datadog, but I use and recommend Cloudcraft[1] for diagramming. As I don't use the cloud I focus more on the manual design tools, but the automatic stuff are pretty neat.
Recently, though, I've been using D2[2] a lot and really liking it. The diagrams don't look as aesthetically pleasing to my eyes, but being able to design everything with a simple language is pretty cool, and helps with automation.

My 2024 review
This year I've started writing about several documentation techniques (as code) in my Documentation as Code series. I definitely want to add at least D2Lang to it.
- D2: Declarative Diagramming – A modern language that turns text to diagrams
- Mermaid ASCII Diagrams
- D2: A New Diagram Scripting Language That Converts Text to Diagrams Instantly

Exploring Goja: A Golang JavaScript Runtime
I work on the D2 project ([0]) and we switched from other Javascript runners (v8go) to Goja. Using a JS runtime with a dependency on cgo means your Go program loses the (huge) benefit of cross-compiling to different architectures, since at build time it gets linked to the architecture-specific libc.
If you're interested in some production code with Goja, this is our code for calling RoughJS [1] from Go in order to produce the hand-drawn diagram look: [2]

Pikchr: A PIC-like markup language for diagrams in technical documentation
While not embedded in markdown, I like d2 [1]. I can use it with org-babel to embed and view the diagrams on emacs. After using graphviz for years, the visual output seems more polished to me. With that said, I want to give pikchr a try.
