## README
# Vega: A Visualization Grammar 
**Vega** is a *visualization grammar*, a declarative format for creating, saving, and sharing interactive visualization designs. With Vega you can describe data visualizations in a JSON format, and generate interactive views using either HTML5 Canvas or SVG.
For documentation, tutorials, and examples, see the [Vega website](https://vega.github.io/vega). For a description of changes between Vega 2 and later versions, please refer to the [Vega Porting Guide](https://vega.github.io/vega/docs/porting-guide/).
## Install
Use npm to install Vega for use in third-party libraries or applications.
Using npm:
```sh
npm install vega
```
If you would like to install the Vega command line utilities (`vg2pdf`, `vg2png`, `vg2svg`), see the [`vega-cli` package](https://github.com/vega/vega/tree/master/packages/vega-cli).
