Questions tagged [ggvis]

The goal of ggvis is to make it easy to describe interactive web graphics in R. It fuses the ideas of ggplot2 and shiny, rendering graphics on the web with vega (so one can draw on the canvas or using svg). It is less flexible than raw d3 or vega, but much more succinct and is tailored to the needs of exploratory data analysis.

From the author(s):

ggvis is a data visualization package for R which lets you:

  • Declaratively describe data graphics with a syntax that is similar to ggplot2.
  • View and interact with the graphics on your local computer, or use them in an interactive web application with shiny.
  • 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.
