I was not aware of this xkcd comic, funny how things seem to pop out. My inspiration was more in the line of Sankey diagrams. Among others, the famous map of Napoleon's invasion of Russia by Minard (http://en.wikipedia.org/wiki/File:Minard.png http://en.wikipedia.org/wiki/File:Minard.png). I've called this representation a "groupflow" but any name would do.
The notion of agreement departs a little bit from the classical fraction of common votes/total votes and instead is based on a vector model of votes, using cosine similarity as a value of agreement. The agreement groups are computed by heuristically optimizing a quantity called the cohesion and which turns out is really correlated to the way people perceive social communities (the old preprint of the first paper: http://arxiv.org/pdf/1107.3231.pdf http://arxiv.org/pdf/1107.3231.pdf).
- specialist 14y agoMinard's graph is brilliant. On my to do list: a graph that shows the loss of voters casting ballots. I needed a way to show how postal balloting disenfranchises voters (what it gives, it equally takes away). Voting age population -> registered to vote -> voter received ballot -> returned ballot -> elections rcvd ballot -> signature verification -> challenged ballots -> overvotes/undervotes, voter intent, adjudication -> tabulated.
- EvilTerran 14y agoActually, now you mention it, I think I remember seeing the author of XKCD mention that he was inspired by Minard's diagram. I'm afraid your paper's too much for my brain on a Sunday morning, but the diagrams and typesetting look really well done :)
