After seeing the announcement by @lauraegerdal of the SEC’s use of dygraphs to visualize market structure, I was inspired to experiment more with the great dygraphs + rCharts. I really wanted to see how responsive dygraphs would be with a fairly large dataset. Some Kenneth French US Industry data seemed just big enough to get a good feel for dygraph’s digestive abilities. See it in action here or click on the screenshot below.

I wanted to analyze the EXIF information in a whole group of photos from a recent trip to Disney World. Of course I decided to use R and throw in some interactive charting with d3.js, rCharts, and and the new catcorrjs. Integrating the amazing and open-source Perl exiftool was a fun bonus. Click here or on the screenshot below for all the details.
On the trip I was baffled by some bad pictures. I realized the reason was ISO 6400, which was unintentionally set by the ring on our s100 when handing the camera to strangers for group shots.
