Dygraphs with Bigger Data | US Industries from Kenneth French

15.11.2013

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 fo...
