Bob's pick this week is Summer Olympic Medals 1896-present by Bill McKeeman.
The data source is Wikipedia, which Bill references. I find his plots much more interesting than staring at tabular data.
His approach to coding this example underscores how many ways there can be to solve a problem. I know my own approaches have varied widely
over the years, usually dictated by time spent and knowledge level at the time.
How do you approach analysis problems like this? Tell us about it here.
