Episode 110: Mapping

SEP 4, 1998
Five ways of mapping the world. One story about people who make maps the traditional way — by drawing things we can see. And other stories about people who map the world using smell, sound, touch, and taste. The world redrawn by the five senses.

Ruslan Enikeev’s Map of the Internet

Very impressive visualization with search capability of the entire Internet. Type in your favorite website and see it on the map.

Data Juice

The Internet Map is the culmination of an exciting project from a team headed by Ruslan Enikeev, in which the world wide web is mapped to produce the visualisation pictured below.  Web traffic from 35o thousand websites are mapped into a system where  circle size corresponds to overall visitors; and the position and proximity to other websites reveals where visitors most commonly surf to and from.  Rendering the graphic in this way shows that sites tend to cluster into groups relating to country of origin, which are represented by the colours in each circle.  Click the image below to explore the map, URL’s can be entered into the search bar on the top left.

LinkedIn Network Map

Toby at tipp(l)ing point

LinkedIn has a network mapping tool too, and it’s very pretty. It’s fairly predictable, the way I have 6 clusters of connections plus a few single unattached individuals – but the thing it brings to my mind most is the people who AREN’T there – the gaps in the network. I suppose some people are just like that. Some of them are in my Facebook network map, so now I want to merge the two of them. This is only the first-level network of course. If we had more dimensions we could show deeper levels – contacts-of-contacts.

As an afterthought, the map seem to show that the co-operators (in blue on the right) are a very cohesive network among themselves – more densely interconnected than my other work-related communities. I suppose that’s because co-operation is more than just a job.
