### Examples

### Builds

If you don't use a package manager, you can [access `vega-spec-injector` via unpkg (CDN)](https://unpkg.com/vega-spec-injector/), download the source, or point your package manager to the url.

`vega-spec-injector` is compiled as a collection of [CommonJS](http://webpack.github.io/docs/commonjs.html) modules & [ES2015 modules](http://www.2ality.com/2014/0
  -9/es6-modules-final.html) for bundlers that support the `jsnext:main` or `module` field in package.json (Rollup, Webpack 2)

The `vega-spec-injector` package includes precompiled production and development [UMD](https://github.com/umdjs/umd) builds in the [`dist` folder](https://unpkg.com/vega-spec-injector/dist/). They can be used directly without a bundler and are thus compatible with many popular JavaScript module loaders and environments. You can drop a UMD build as a [`<script>` tag](https://unpkg.com/vega-spec-injector) on your page. The UMD builds make `vega-spec-injector` available as a `window.vegaSpecInjector` global variable.
