Over at Flowing Data, Nathan has published an interesting visualization about spread of obesity.

While the above chart is quite interesting, it doesn’t offer much insight in to the data. There are a few drawbacks,

• Understanding obesity trends for a given state over the years is hard due to the layout and format of the chart.
• Finding which states are experiencing most obesity growth rates is not possible
• Ironically, the chart itself is obese. It takes too much space to explain the data.

Nevertheless, the chart looks cool and can be reused with smaller data-sets (quarterly trends or just for a few years). So let’s recreate the same in Excel. While we are at it, let’s also build an alternative visualization to explore the obesity data.
