Plotly.js is a standalone JavaScript data visualization library, and it also powers the Python and R modules named plotly in those respective ecosystems (referred to as Plotly.py and Plotly.R).

Plotly.js can be used to produce dozens of chart types and visualizations, including statistical charts, 3D graphs, scientific charts, SVG and tile maps, financial charts and more.

Install a ready-to-use distributed bundle

npm i --save plotly.js-dist-min

and use import or require in node.js

// ES6 module
import Plotly from 'plotly.js-dist-min'

// CommonJS
var Plotly = require('plotly.js-dist-min')

You may also consider using plotly.js-dist if you prefer using an unminified package.

In the examples below, the Plotly object is added to the window scope by the script tag. The newPlot method is then used to draw an interactive figure as described by data and layout into the desired div here named gd. As demonstrated in the example above, basic knowledge of HTML and JSON syntax is enough to get started, i.e., with or without JavaScript! To learn and build more with plotly.js, please visit the plotly.js documentation.

<head>
    <script src="https://cdn.plot.ly/plotly-4.2.0.min.js" charset="utf-8"></script>
</head>
<body>
    <div id="gd"></div>

    <script>
        Plotly.newPlot("gd", /* JSON object */ {
            "data": [{ "y": [1, 2, 3] }],
            "layout": { "width": 600, "height": 400}
        })
    </script>
</body>

Alternatively, you may consider using native ES6 import in the script tag.

<script type="module">
    import "https://cdn.plot.ly/plotly-4.2.0.min.js"
    Plotly.newPlot("gd", [{ y: [1, 2, 3] }])
</script>

Fastly supports Plotly.js with free CDN service. Read more at https://www.fastly.com/open-source.

While non-minified source files may contain characters outside UTF-8, it is recommended that you specify the charset when loading those bundles.

<script src="https://cdn.plot.ly/plotly-4.2.0.js" charset="utf-8"></script>

Please note that as of v2 the "plotly-latest" outputs (e.g. https://cdn.plot.ly/plotly-latest.min.js) will no longer be updated on the CDN, and will stay at the last v1 patch v1.58.5. Therefore, to use the CDN with plotly.js v2 and higher, you must specify an exact plotly.js version.

plotly.js supports using MathJax v3 or v4 to render mathematical expressions within plots.

MathJax is not included in the plotly.js bundle, so it must be loaded separately as a script on the webpage.

For MathJax v4:

<script src="https://cdn.jsdelivr.net/npm/mathjax@4.1.3/tex-svg.js"></script>

For MathJax v3:

<script src="https://cdn.jsdelivr.net/npm/mathjax@3.2.2/es5/tex-svg.js"></script>

When MathJax is available, any string contained within $..$ signs will be rendered using the MathJax engine. This applies to plot titles, axis labels, tick label text, and annotations.

plotly.js's use of the MathJax svg renderer should not prevent using other MathJax renderers elsewhere on the page, nor will it affect the global MathJax config. See devtools/test_dashboard/index-mathjax3chtml.html for an example of a webpage which uses the MathJax chtml renderer in the main page, and also displays Plotly charts containing MathJax equations rendered as svg.

You may simply load the virtual-webgl script for WebGL 1 (not WebGL 2) before loading other scripts.

<script src="https://unpkg.com/virtual-webgl@1.0.6/src/virtual-webgl.js"></script>

There are two kinds of plotly.js bundles:

1. Complete and partial official bundles that are distributed to npm and the CDN, described in the dist README.
2. Custom bundles you can create yourself to optimize the size of the bundle depending on your needs. Please visit CUSTOM_BUNDLE for more information.

If your library needs to bundle or directly load plotly.js/lib/index.js or parts of its modules similar to index-basic in some other way than via an official or a custom bundle, or in case you want to tweak the default build configurations, then please visit BUILDING.md.

Official plotly.js documentation is hosted at https://plotly.com/javascript.
