After a suggestion from a friend, I wanted to see how many pushups I could do in a year. Predictably, I got sick in May and the plan fizzled out. Regardless, I tracked my progress using a Google Sheet. Thanks to Tabletop.js, I can retrieve the contents of my Google Sheet (as JSON) in Javascript. The result is then plotted (again, completely in Javascript) using Bokeh.js, which I found out about at PyCon (H/T: Sarah Bird)
