I originally implemented an absolute chart, but at the time JavaScript was so much higher than everything else for the most growth and top charts that it made them hard to read. I tried log next but at some point I must've realized what I really wanted was just a simple ranking, which is why I landed on a bump chart.
But that was years ago and I'd be curious to see how they look now. An option to toggle the y axis scale could be interesting. Thanks for the feedback!
