Thanks, sebg, for submitting this! The main difference between this and some other heatmap charts is the UI design, and the fact that is a 1 year moving window of day aggregated data. Thanks for sharing all of the other heatmap examples in the comments, many of which I haven't seen before. This is still in the early stages so if you have any questions or suggested improvements, just comment them here - I'd love to hear them!
