I enjoyed the idea of these heatmaps and charting. I added the sparkline graph last week after I saw them on Chris's website. I may create a separate web site page to keep these. I don't know how useful they are, but they are just cool. I would also love a way to display some of the JetPack graphs.
These are the yearly JetPack stats from 2010, the year Automattic first offered the, to 2019.

But I get more "responses" that I did in earlier years. I suspect more of these are from semantic responses on other platforms, Facebook, Twitter, Instagram since. It's, and the time I started using some of the IndieWeb software.
Below is the Internet Archive graph for 2018, compared to 2012. Traffic has fallen off.
