During the first week of the “Developing Data Products” MOOC on Coursera, one of the lessons deals with GoogleVis. This is one of the ways to publish and animate your R charts. In practice GoogleVis provides an interface between R and the Google Charts Tools, allowing you to create interactive web charts from R without uploading your data to Google. I have found the lesson a little bit confusing and I felt the need to find out a little bit more. So, I googled for it, and I found this article on r-bloggers, which eventually pointed to this little but comprehensive free tutorial on www.datacamp.com (offering verified tests at each steps and a certificate of completion). I thought it was a little pearl that deserved to be shared once more.
