Market and trust evidence

Edition not yet matched

No exact skills.sh identity match is available for this repository. Repository adoption and freshness remain visible above; install momentum is not inferred.

Trust analysis is a screening signal, not a security warranty. Read the ranking and trust methodology.

In practice

Written by AI from this repository’s README · high confidence

Covering many chart families, including WebGL and maps, usually means combining several separate libraries.

Use it when

When you need a wide range of chart types in the browser, loaded as a node module or from a CDN script tag.

Not the right pick when

The complete bundle is heavy, so the README steers you to partial official bundles or custom bundles to control size.

Capabilities

dozens of chart types including statistical, 3D and scientific charts
SVG and tile maps plus financial charts
load as a node module or via a CDN script tag
complete and partial official bundles on npm and the CDN
custom bundles to optimize bundle size
MathJax version two or three support for typeset labels

Cost: Free and open source

Install

Derived from the published package name in the repository, not from a model.

Changed

Update sendDataToCloud modebar button to upload chart to Plotly Cloud [#7802, #7852, #7854]
NOTE: The Plotly Cloud endpoint for receiving charts is not yet functional, so this button won't complete the upload.

Fixed

Fix stale scattergl error bars after toggling traces with mixed error bar visibility [#7773], with thanks to @JulienIcon for the contribution!
Fix "unrecognized GUI edit: selections[0]..." warnings emitted after making a box or lasso selection and then calling Plotly.react() [#7836]
Fix geo fitbounds to choose a compact longitude range when point data straddles the antimeridian [#7837], with thanks to @SharadhNaidu for the contribution!
Preserve XML structural entities during decode when exporting SVG [#7838]
Fix Plotly.Fx.hover crash on scattermap traces when called programmatically with a pointNumber selection [#7882]

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.

Load as a node module

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.

Load via script tag

The script HTML element

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-3.7.0.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-3.7.0.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>.

Un-minified versions are also available on CDN

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-3.7.0.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.

MathJax

You can load either version two or version three of MathJax files. For example:


<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-AMS-MML_SVG.js"></script>


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

When using MathJax version 3, it is also possible to use chtml output on the other parts of the page in addition to svg output for the plotly graph.

Please refer to devtools/test_dashboard/index-mathjax3chtml.html to see an example.

Need to have several WebGL graphs on a page?

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>

Bundles

There are two kinds of plotly.js bundles:

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

Alternative ways to load and build plotly.js

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.
