An introduction to the concept of a Cycle Space.
CycleSet is a game of linear algebra and graph theory, where the goal is to find a nonempty collection of the subgraphs you are presented with whose symmetric difference is the graph with no edges. That sounds a lot more complicated than it is - click around for a few minutes and you should get the idea.
Currently purescript-react doesn't support SVG DOM properties, so this is using a modified
version of purescript-react, DOM.purs.
