#SWDChallenge - Sept '18

This chart is my contribution to the september 2018 #SWDChallenge.

I wanted the chart to focus on rank shifts so I designed it this way:

colours focus attention on rank shifts; any other information (such as precentages) gives the reader a deeper understanding, but uses less eye-catching colours (i.e. greys) in order to not disturb the main message
two distinct colours differentiate rise and fall, respectively lime-green and pink-red (more on this colour-blindness friendly palette below)
the chart is vertically oriented, so that shapes of the chords themselves indicate a rise or a fall

Also, even if my first idea was to use a flow chart, it was more appealing and fun to use a circular flow chart :-) Many thanks to Nadieh Bremer for sharing How to create a Flow Diagram with a Circular Twist.

Finally, regarding the color palette, I first use a basic green/red, but @storywithdata immediatly noticed that it was not color-blindness friendly. I first didn't know how to modify the palette. @visualizingdata brought me the response I was looking for in its wonderfull blog five ways to design for red-green colour-blindness (I choose option #2).
