Show HN: Reladraw – A diagram language where you decide where to place things

Reladraw is a diagram language that allows users to define diagrams and have control over their layout. It's a compromise between auto-placement languages like Mermaid and powerful software like Draw.io. The language works well for both humans and agents, and a playground is available on the Github link. Users can try it out without installation or install it via npm and use it with agents like Claude.
