Visualising World Map through Facebook Friendships

[Flora Salim]

Hi all,
Have you seen this beautiful work by Paul Butler, an intern in Facebook?
http://www.facebook.com/notes/facebook-engineering/visualizing-friendships/469716398919

He used R statistical tool to plot points, and draw lines to visualise friendship links in FB - and what he got is a detailed world map!

Cheers,
Flora

Hi, cool, I sent to Przemek yesterday the code, how to map gps
coordinates on an world map image. Best, Martin

Hey, this is great... I really like this map!
Indeed, the code for getting xy coord on the map works and it's cool..
but in our case, we're operating on different scale, where everything is
almost rectangular.. I am not sure how google translates it to the
screen, but they say it's equidistant from all edges. In principle -
this is wrong, because a rectangle mapped od global coordinate grid
would cut some sort of trapezoid out of it :-)

But that's not important... I think we will calibrate it just by eye or
something (unless we do earth-wide visualisations)

I wrote a tutorial today on running agent based system on google maps
(with street detection).

Can you read though this and let me know what you think ? Is it too
geeky, or not geeky enough ? ;-)
I hope it's quite understandable, but if it's not, please point it out,
I am happy to explain/discuss it...

cheers!

Is anyone familiar with the google map and chart API?

Not sure it is directly usable from processing, but perhaps there is something in there that can be applied in the cluster?
