I built DiagramIDE because I wanted a more modular way to handle diagramming-as-code. It’s a Rust-based GUI (EGUI) where you can split logic, data, and rendering into separate windows. Instead of one giant DSL file, you can script components in Tcl, define relationships in Prolog, and pipe the results into Pikchr for the final render.
Fair warning: it’s an early alpha and still quite rough around the edges. I’ve been dogfooding it for my own work so it’s definitely functional but expect unexpected.
Shortest way to try it out is a compiled binary release: https://github.com/exlee/pikchr.pl/releases/tag/latest
