Data manipulation and transformation are done in R, and the graphics are rendered in a web browser, using Vega. For RStudio users, ggvis graphics display in a viewer panel, which is possible because RStudio is a web browser.
Presently, ggvis is in an alpha stage, and its API is still evolving. We strongly recommend that you do not rely on this for production, but feel free to explore. For questions and other discussion, please use mailing list.
