and use the plotly.js dist file(s). More info here.

Read the Getting started page for more examples.


Starting in v1.15.0, plotly.js ships with several partial bundles (more info here).

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:

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

// Load in the trace types for pie, and choropleth

module.exports = Plotly;

Then elsewhere in your code:

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

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:

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