This is a very cool project...I haven&#x27;t yet had a chance to use it in production, but the fact that Winston Chang and Hadley Wickham are using it to render interactive graphics via R...i.e. the ggvis [1] library, i.e. the interactive successor to ggplot2...makes me think that it must be a pretty solid library.<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;rstudio&#x2F;ggvis" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rstudio&#x2F;ggvis</a>
