Caveats:

1. Geographical locations are entirely based on self-reported locations.

2. I'm using OpenStreetMaps's Nominatim geocoding service. It doesn't always know where you are.

3. Package contributors aren't being plotted at the moment.

A small suggestion: it may be more insightful if you remove merge commits; I would say I'm definitely overcounted in the current results.

[Jiahao Chen]

Fair enough, but that would mean actually parsing the commit history :)

Strange that GitHub excludes merge commits on their site, but not in their API.

[Stefan Karpinski]

I wonder if there isn't some API option to exclude them – they must already have this information, since they use it on the site.

[Westley Hennigh]

I think the issue is that the github api has two methods for getting commit history. One contains detailed information and excludes merge commits, but is only available for the top 100 contributors. The other is available for all contributors, but as just a single "number of commits".
