A live sample would be much more interesting, both would be best. I'd be most interested in the meta keys. As a scandinavian especially {}, [] etc. buttons are very awkward to press. Infact, so are most special characters used in programming.

As mentioned, auto-complete and similar functionality change the heatmap, but that's what people actually press. This data would be alot better for actual use.

Though I don't mean it as a scold, it wasn't really in the hands of the author to collect such vast amounts of live data, and surely a lot more work than was his intension.
