When I need a tool to organize things with a graph I usually just use yEd. You can do a surprising number of things with it: - Graph layout algorithms - Graph scoring (centrality etc.) - Variety of node types - You can add custom node types (to a point), even use pictures of things - Cross-platform (not open source sadly) - Swim-lanes, grids, grouping structures - Graphs are saved as .graphml xml and so on. It's not perfect, I wish I could also just drop in multi-media type files and turn them into node representations. https://www.yworks.com/products/yed https://www.yworks.com/products/yed?
