Florence Nightingale Circumplex Chart
I was taken to Florence Nightingale's Wiki page during a recent research, and one of the interesting things I noted was her contribution to statistics. It came to me as a pleasant surprise that she is credited with inventing the polar area diagram, or occasionally the Nightingale rose diagram, which is equivalent to a modern circular histogram.
Following the completion of my project and in my weekend to spare, I devoted time to recreating the chart in Excel. It took a combination of Doughnut-Pie-and XY charts and close to four hours to finish it. The colors are a bit darker, the values are approximate and the labels differently oriented, yet the chart looks fairly close to the original as is shown by the picture below.
