About this blog

The data visualizations on this blog are the result of my "data tinkering" hobby, where I tackle a new data analysis problem every weekend. If I find something interesting, I report my findings here to share with the world.

If you would like to use one of my graphs on your website or in a publication, please feel free to do so with attribution, but I would appreciate it if you email me first to let me know.
