This visualization was created for the Eyeo Festival visualization challenge. The challenge was to have a creative approach in showing 2010 US Census data, preferably not as map. What you see here is housing data for all counties in the US, actually as a scatterplot. Here are some instructions and things to note:

• the y-axis shows population. Note the logarithmic scale
• the x-axis for the bubbles shows the number of vacant homes per population
• the outer circle of the bubble shows the total number of homes
• the inner bubble shows the vacant number of homes
• each bubble has a line that connects the bubble to yet another scale: the population / home ratio
• you can use the left- and right arrow keys to browse through all the states (make sure that the Applet has the focus; if not, click once on the Applet with your mouse to give it focus).
• if you move your mouse over a bubble, you can highlight an individual bubble, and at the top right you can see some exact numbers for your selection

There are some interesting things to look for:

• counties that have more homes than people
• or, counties that have more than 50% vacant homes
Enjoy! (The Applet is 8Mb due to the size of the data, so just wait until the data has been loaded)
