I have an Untagle game on my phone... is there an SVG editor that could do something similar?

I've found Graphviz / DOT to be surprisingly handy at times:

* https://en.wikipedia.org/wiki/DOT_(graph_description_languag...

"this is a simplified representation" :D

Wonder if there's some more ideal way to lay out those so they are less of a tangled web. This graph makes me want an adjacency list.
