Pando is a work in progress, general purpose graph editor. The long term vision for the project can be found here.
Currently Pando is not yet usable, but has some of the key pieces in place including a basic UI framework based on Neovide's new wgpu renderer Vide that I'm calling Aspen.
Pando is named after the Pando tree, which is a quaking aspen clonal colony that is thought to be the largest single connected organism in the world.
