I have been thinking of how you can visualise different data after attending CYSWIK Pre Valentines seminar. Recently I read about dopplr at Jilltxt. Dopplr is a tool for sharing information about your travels.
One way of visualising the travels over time is what is shown in the image of Obamas travels during 2008. A kind of Annual report represented by images (including a carbon footprint).
Another visualising tool that I stumbled upon last week is the Media Cloud from Berkman centre where they started to develop a tool for visualising media flows:
An older similar visualisation tool that I have used before is Blog pulse. Here you can look at trends of issues appearing in blogs or conversations developed between the blogs:
In digg they use the data and show it in several different ways to display how “popular” a certain web page or image is in the sense how many persons have “digged” it. Look for example on the stack or swarm here:
The visualisations are still a bit hard to understand at first, e.g. it’s not that the images make you immediately understand dopplr if you haven’t came across it before. However, it is fascinating and I will continue to look for these kind of applications and see if I can find more examples.
