Maps made of tweets


This is a lovely image was created by the Visual Insights team at Twitter from billions of geo-tagged tweets posted since 2009. Look closely and you can pick out the roads between cities – even a little bright spot that is Brighton (directly south of London).


You can see more images on the Twitter Flickr account – and some commentary on this blog post from Miguel Ros.

Facebook planet


This image has been on my computer desktop and on my mind since I saw it in December. High time I shared it here, really.

It’s a data visualisation of 10 million pairs of friends on Facebook and where they live in relationship to one another, created by an intern on Facebook’s data infrastructure engineering team. Read the original blog post in full – it is fascinating stuff.

As Ian Tait points out, what’s amazing is that there is no map underneath, and yet you can pick out the shapes of the continents.

Interesting too are the gaps – China, Brazil and Russia are underrepresented, perhaps due to the fact that other social networks are more prevalent in those territories (RenRen, Orkut and Vkontakte respectivelY).
