Drink blood, control humans v. take brain, repair ship

Had marked this bit in the Guardian a while ago as a “read it later” article: Every Doctor Who villain since 1963 (part of the generally excellent DataBlog, which covers all manner of data and visualization [often UK-focused, but still broadly interesting] — and which frequently makes the data used for infographics publicly available through Google Docs). How had I forgotten to come back to it? It’s fascinating!

Also, had forgotten about IBM’s weirdly-named Many Eyes, which lets you run visualizations of your own (and which is used for one of the above bubble graphs).
