Randall Hand is a computer graphics programmer and news junky that's been working in the field for the last 15 years. He's responsible for visualizations generated on some of the most powerful supercomputers in the world, ytnef, mullion support in ParaView, and VizWorld.com.
We used our BI software to generate an interactive dashboard to display the data concerning Facebook’s 500 million users. Now you can visualize it, you can see so much more than just a number!
The dashboard contains 3 visualizations which all show different relationships.
The first, the treemap, shows the number of users in July 2010 in relation to the percentage penetration (number of people on Facebook as a percentage of the country’s population). The size of each individual box within the treemap shows the total number of Facebook users in the country. The strength of the color shows the percentage penetration, with the darkest blue being attributed to a higher percentage of users, and the lightest blue being attributed to the lowest.
The second visualization is the geovisualization, or heat map. We have chosen graduated circles to display the information but you can change it back to the original heatmap format by clicking on “Rendering Mode” in the bottom left hand corner. Here we see the relationship between the population and the percentage penetration. The size of the graduated circles show proportionately the population size, and the number inside demonstrates the percentage penetration. A very simple but a highly visual representation, the heatmap is probably the best way to get an overall geographical idea of where Facebook’s users are around the world.
Lastly, our third chart is the classic pie chart. We have used the filters to filter out any country with a population of less than 10 million. This gives us a nice overview of the relationship between the percentage penetration and the number of users. We have also chosen to display the percentage penetration measure by size, to make it really clear which countries have a high percentage (USA, UK) and which have a low percentage (India, Mexico).
