We had some curious people ask what was buried in that mass of red dots in the lower left corner of the graph (see previous post), so we zoomed in on it. Another surprise! There are some geographic coordinates buried in there. So, here it is, a zoom of lower left corner of the graph, showing a somewhat familiar looking outline. If you look closely you'll even see the path of Katrina in there. We still don't know exactly what each data point represents. It would be fun to put up another graph and make each data point clickable with a link to its location on the web. Comments
