# googleVis 
[![Travis-CI Build Status](https://travis-ci.org/mages/googleVis.svg?branch=master)](https://travis-ci.org/mages/googleVis)   [![CRAN\_Status\_Badge](http://www.r-pkg.org/badges/version/googleVis)](https://cran.r-project.org/package=googleVis/) ![downloads](http://cranlogs.r-pkg.org/badges/grand-total/googleVis)


The googleVis package provides an interface between R and the [Google's charts tools](https://developers.google.com/chart/). 
It allows users to create web pages with interactive charts based on R data frames. Charts are displayed locally via the R HTTP help server. 
A modern browser with Internet connection is required and for some 
charts a Flash player. The data remains local and is not uploaded to 
Google.

You find [examples](https://CRAN.R-project.org/package=googleVis/vignettes/googleVis_examples.html) of all googleVis function on [CRAN](https://cran.r-project.org/package=googleVis/). Perhaps the best known example is the [motion chart](http://mages.github.io/googleVis/WorldBank.html), popularised by [Hans Rosling](http://www.gapminder.org) in his [2006 TED talk](http://www.ted.com/talks/hans_rosling_shows_the_best_stats_you_ve_ever_seen). 

Please read [Google's Terms of Use](https://developers.google.com/terms/) before you start using the package. 

## Installation

You can install the stable version from
[CRAN](https://cran.r-project.org/package=googleVis/):

```s
install.packages('googleVis')
```

To install the current development version from github you need the [devtools package](https://cran.r-project.org/package=devtools/) and the other packages on which googleVis depends:

```s
install.packages(c("devtools","jsonlite", "knitr", "shiny", "httpuv"))
```

To install googleVis run:
```s
library(devtools)
install_github("mages/googleVis")
```

## Usage

```s
library(googleVis)
?googleVis
demo(googleVis)
```

See the googleVis package [vignettes](https://cran.r-project.org/package=googleVis/) for more details.
