Sure that's possible. I saw Matt Mackall do it for Mercurial first: https://www.selenic.com/blog/?p=626 https://www.selenic.com/blog/?p=626 In rust, there's cargo-graph to do this for your packages: https://github.com/kbknapp/cargo-graph https://github.com/kbknapp/cargo-graph I used that on Servo once see PNG at https://dirkjan.ochtman.nl/files/servo-graph.png https://dirkjan.ochtman.nl/files/servo-graph.png or SVG at https://dirkjan.ochtman.nl/files/servo-graph.svg https://dirkjan.ochtman.nl/files/servo-graph.svg. From these explorations, I think the four color theorem-type planarity or connectedness is actually less important than a lack of cycles for the perceived complexity, or the difficulty encountered due to that complexity.
