CompGraph

About

This is a javascript library for doing hierarchical graph layout (similar to GraphViz) in JavaScript.

Vision

While GraphViz has fantastic layout algorithm, it is limited in the available output formats and lacks dynamic features. The hops is that with HTML+Javascript we can benefit from that ecosystem:

• Should be able to produce self-contained files by copying the layout library. Eliminating installation steps of graphviz/image viewers for users.
• We can delegate graph styling to CSS files.
• Can build dynamic elements with javascript on top: Explore/expand graph by clicking, tooltips, highlight selected edges, jump to source/target, View/hide layers, ...

Status

• Some basic layout algorithms implemented
• Have a prototype (sched_proto.html) to show dynamic popups on click
• Playground file to enable/disable layout features and help debugging

Planned

• Integrate into LLVM and provide as an alternative to graphviz
