Creating Visualization Plugins

Visualizations in Superset are implemented in JavaScript or TypeScript. Superset comes preinstalled with several visualizations types (hereafter "viz plugins") that can be found under the superset-frontend/plugins directory. Viz plugins are added to the application in the superset-frontend/src/visualizations/presets/MainPreset.js. The Superset project is always happy to review proposals for new high quality viz plugins. However, for highly custom viz types it is recommended to maintain a fork of Superset, and add the custom built viz plugins by hand.

Note: Additional community-generated resources about creating and deploying custom visualization plugins can be found on the Superset Wiki


In order to create a new viz plugin, you need the following:

  • Run MacOS or Linux (Windows is not officially supported, but may work)
  • Node.js 16
  • npm 7 or 8

A general familiarity with React and the npm/Node system is also recommended.

Creating a simple Hello World viz plugin

To get started, you need the Superset Yeoman Generator. It is recommended to use the version of the template that ships with the version of Superset you are using. This can be installed by doing the following:

npm i -g yo
cd superset-frontend/packages/generator-superset
npm i
npm link

After this you can proceed to create your viz plugin. Create a new directory for your viz plugin with the prefix superset-plugin-chart and run the Yeoman generator:

mkdir /tmp/superset-plugin-chart-hello-world
cd /tmp/superset-plugin-chart-hello-world

Initialize the viz plugin:

yo @superset-ui/superset

After that the generator will ask a few questions (the defaults should be fine):

$ yo @superset-ui/superset

create test/__mocks__/mockExportString.js
create test/plugin/buildQuery.test.ts
create test/plugin/transformProps.test.ts
create types/external.d.ts
create src/images/thumbnail.png

To build the viz plugin, run the following commands:

npm i --force
npm run build

Alternatively, to run the viz plugin in development mode (=rebuilding whenever changes are made), start the dev server with the following command:

npm run dev

To add the package to Superset, go to the superset-frontend subdirectory in your Superset source folder run

npm i -S /tmp/superset-plugin-chart-hello-world

If you publish your package to npm, you can naturally install directly from there, too. After this edit the superset-frontend/src/visualizations/presets/MainPreset.js and make the following changes:

import { SupersetPluginChartHelloWorld } from 'superset-plugin-chart-hello-world';

to import the viz plugin and later add the following to the array that's passed to the plugins property:

new SupersetPluginChartHelloWorld().configure({ key: 'ext-hello-world' }),

After that the viz plugin should show up when you run Superset, e.g. the development server:

npm run dev-server
