I've been working on a similar project in my spare time to create tools for interactive technical blogs [1]. It's funny, in the past day I've seen two projects that I would say have the same goals as me, idyll being one of them.
What are the possibilities around contributing to idyll? Building on top of it? Is it as simple as writing my own components?
I'm specifically interested in uis to define data structures. One of the more annoying things I found working with d3 to create graphs (as in graph theory) was defining the graphs procedurally, so I built a ui to define graphs graphically.
