Sometime this month, I have to travel to NYC, and will need access to WiFi. Hopefully, it will be free. But where to start looking? Well, the NYC Open Data program happens to have a 2010 vintage list of WiFi locations in the whole city. Each entry has complete name and address information, along with lat/long. Free vs Fee is another one of the dimensions of the data. Here is what I did with the data in short order, using Tableau Public. The data set includes a City field, which I thought would have five entries, one for each Borough. However, it seems to be a collection of the Borough names along with neighborhood names. The city 'New York' is really Manhattan Borough, which is of interest to me for this trip. There are quite a few listings there. The other Borough names are in the list of Cities, but contain few locations each, serving, I suspect, as a catch all when no neighborhood is appropriate.

Saturday, June 2, 2012, ESPN More Sports' Stats & Info site carried a special look at Johan Santana's history making no-hitter in a New York Mets - St Louis Cardinal's match-up. The story included a playing field visualization of each out in the game, using Tableau Public. The visualization places a circle at the location of each out. The circles are color-coded by type of play (fly out, ground out, strike out). The inning in which an out occurred is encoded by varying the size of the circle; all outs in inning one supposedly one size, inning two, slightly larger, and so on). Take a look at the image below:
