Nueva version de GoogleVis

The googleVis package provides an interface between R and the Google Charts API. It allows users to create web pages with interactive charts based on R data frames. Charts are displayed locally via the R HTTP help server. A modern browser with Internet connection is required and for some charts a Flash player. The data remains local and is not uploaded to Google.

You find examples of all googleVis function on CRAN. Perhaps the best known example of the Google Chart API is the motion chart, popularised by Hans Rosling in his 2006 TED talk
