RStudio cloud service in the works?

An interesting result popped up when I searched for RStudio cloud this morning: RStudio.cloud from RStudio itself.

“Kick the tires to your hearts delight – but don’t plan on taking a cross-country trip just yet,” the service warns on its home page.

There are many tools around to help turn data into graphics, but they can carry hefty price tags. The cost can make sense for professionals whose primary job is to find meaning in mountains of information, but you might not be able to justify such an expense if you or your users only need a graphics application from time to time, or if your budget for new tools is somewhat limited.
