It is for this reason that my visualization group have chosen to present data on this topic to the class. Facebook is a relevant topic in our course, as social medium is a highly popular form of media in contemporary society. We researched many statistics on the use of Facebook within several countries, and broke this down to two main sites which are recent and reliable sources. These were:

Our visualization (that is, making our 'invisible' data into something visible') consists of different sized and coloured circles which form a particular order. These circles represent several things. Firstly, each circle is given a different colour. This is to give each country its own identity, and allows one to follow the order easily with their eyes. Next, the circles range in size. This size represents the overall population of the country. For example, the United States circle is much larger than the others, as there are over 300 million residents living here. Finally, the order of the of the circles ranks the countries in order of which has the highest percentage of Facebook users in regards to their population size. For instance, Canada is positioned first, as 53.5% of their country uses Facebook; a percentage higher than any other country in the world.
Our visualization represents the top 20 countries of Facebook users around the world. This particular visualization is effective because of the fact that it contains several types of data within the one image, and therefore clearly and effectively answers the question of who uses Facebook around the world. A way of making this visualization more effective would be to perhaps include more than the top 20 countries, to give viewers a ranger set of data.
