The Big Society is a society in which individual citizens feel big: big in terms of being supported and enabled; having real and regular influence; being capable of creating change in their neighbourhood. Does our society pass this test at the moment?
Well, only 4 out of 10 of us believe that we can influence local decisions. Only 1 in 33 of us attend public meetings. We feel anger and frustration at the recent behaviour of both the City and Westminster and relatively powerless to change them. We are often anonymous tax-payers without a real sense of how our money gets spent. Most of us try to be reasonably good citizens but our influence seems very small.
The Big Society is a powerful vision to change this, creating a nation of empowered citizens and communities. It has been articulated by Prime Minister David Cameron, but is linked to some of the best ideas across the political spectrum.
We believe that by working in partnership with communities, businesses, charities and foundations and statutory bodies we can generate innovative solutions which can strengthen local neighbourhoods.

‘Pues tal vez no sea el mejor, pero es del que más contento estoy’.
‘El máximo nivel de interactividad hoy en día es el videojuego, puesto que te identificas con el personaje. En esta infografía el usuario es parte del gráfico’.
Visualización de las relaciones de amistad en Facebook.
Por Paul Butler, ingeniero de la red social.
‘Visualizing data is like photography. Instead of starting with a blank canvas, you manipulate the lens used to present the data from a certain angle.
When the data is the social graph of 500 million people, there are a lot of lenses through which you can view it. One that piqued my curiosity was the locality of friendship. I was interested in seeing how geography and political borders affected where people lived relative to their friends. I wanted a visualization that would show which cities had a lot of friendships between them.
I began by taking a sample of about ten million pairs of friends from Apache Hive, our data warehouse. I combined that data with each user’s current city and summed the number of friends between each pair of cities. Then I merged the data with the longitude and latitude of each city.
At that point, I began exploring it in R, an open-source statistics environment. As a sanity check, I plotted points at some of the latitude and longitude coordinates. To my relief, what I saw was roughly an outline of the world. Next I erased the dots and plotted lines between the points. After a few minutes of rendering, a big white blob appeared in the center of the map. Some of the outer edges of the blob vaguely resembled the continents, but it was clear that I had too much data to get interesting results just by drawing lines. I thought that making the lines semi-transparent would do the trick, but I quickly realized that my graphing environment couldn’t handle enough shades of color for it to work the way I wanted.
Instead I found a way to simulate the effect I wanted. I defined weights for each pair of cities as a function of the Euclidean distance between them and the number of friends between them. Then I plotted lines between the pairs by weight, so that pairs of cities with the most friendships between them were drawn on top of the others. I used a color ramp from black to blue to white, with each line’s color depending on its weight. I also transformed some of the lines to wrap around the image, rather than spanning more than halfway around the world.
After a few minutes of rendering, the new plot appeared, and I was a bit taken aback by what I saw. The blob had turned into a surprisingly detailed map of the world. Not only were continents visible, certain international borders were apparent as well. What really struck me, though, was knowing that the lines didn’t represent coasts or rivers or political borders, but real human relationships. Each line might represent a friendship made while travelling, a family member abroad, or an old college friend pulled away by the various forces of life.
Later I replaced the lines with great circle arcs, which are the shortest routes between two points on the Earth. Because the Earth is a sphere, these are often not straight lines on the projection.
When I shared the image with others within Facebook, it resonated with many people. It’s not just a pretty picture, it’s a reaffirmation of the impact we have in connecting people, even across oceans and borders’.
