## Quick start options

### Install with npm

```bash
npm install plotly.js-dist
```

and import plotly.js as `import Plotly from 'plotly.js-dist';` or `var Plotly = require('plotly.js-dist');`.

### Use the plotly.js CDN hosted by Fastly

```html
<!-- Latest compiled and minified plotly.js JavaScript -->
<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>

<!-- OR use a specific plotly.js release (e.g. version 1.5.0) -->
<script src="https://cdn.plot.ly/plotly-1.5.0.min.js"></script>

<!-- OR an un-minified version is also available -->
<script src="https://cdn.plot.ly/plotly-latest.js" charset="utf-8"></script>
```

and use the `Plotly` object in the window scope.

### Download the latest release

[Latest Release on GitHub](https://github.com/plotly/plotly.js/releases/)

and use the plotly.js `dist` file(s). More info [here](https://github.com/plotly/plotly.js/blob/master/dist/README.md).

#### Read the [Getting started page](https://plot.ly/javascript/getting-started/) for more examples.


## Modules

Starting in `v1.15.0`, plotly.js ships with several _partial_ bundles (more info [here](https://github.com/plotly/plotly.js/blob/master/dist/README.md#partial-bundles)).

Starting in `v1.39.0`, plotly.js publishes _distributed_ npm packages with no dependencies. For example, run `npm install plotly.js-geo-dist` and add `import Plotly from 'plotly.js-geo-dist';` to your code to start using the plotly.js geo package.

If none of the distributed npm packages meet your needs, and you would like to manually pick which plotly.js modules to include, you'll first need to run `npm install plotly.js` and then create a *custom* bundle by using `plotly.js/lib/core`, and loading only the trace types that you need (e.g. `pie` or `choropleth`). The recommended way to do this is by creating a *bundling file*. For example, in CommonJS:

```javascript
// in custom-plotly.js
var Plotly = require('plotly.js/lib/core');

// Load in the trace types for pie, and choropleth
Plotly.register([
    require('plotly.js/lib/pie'),
    require('plotly.js/lib/choropleth')
]);

module.exports = Plotly;
```

Then elsewhere in your code:

```javascript
var Plotly = require('./path/to/custom-plotly');
```

To learn more about the plotly.js module architecture, refer to our [modularizing monolithic JS projects](https://plot.ly/javascript/modularizing-monolithic-javascript-projects/) post.

#### Non-ascii characters

Important: the plotly.js code base contains some non-ascii characters. Therefore, please make sure to set the `charset` attribute to `"utf-8"` in the script tag that imports your plotly.js bundle. For example:

```html
<script src="my-plotly-bundle.js" charset="utf-8"></script>
```
