A visualization of some data from the 2010 U.S. Census. This was created for the University of Illinois Coursera class on data visualization.

My submission uses data on the population and area of US states, based on the 2010 census, and was obtained from the website. The data are displayed using bar charts built with d3 and the visualization includes an interactive sorting feature and a text display if you hover the mouse over a bar. Because area and volume are less effective in communicating quantitative differences than length, I was interested in the idea of using length to display area or volume. I applied the guideline of using desaturated colors for the fills of the bars. I included density as a sorting option, but didn’t display it as a bar since it is computable from population and area. This is motivated by Edward Tufte’s guidelines of removing redundent elements of the visualization.
