Adding an example to the Gallery

We welcome anyone to submit an example to our gallery.


Add your example to the website in the directory packages/website/src/examples. Before submitting a pull request, make sure you have done the following:

  • Made a directory with all of the required files
  • Updated the list of examples in examples-list.tsx to include yours
  • Added light and dark screenshots of your example to the _previews directory as png files
  • Verified the example works in each of our supported UI frameworks (how-to guide here)

Required Files

Your directory should be called your-example-name. In it, you will need to have files for all of our supported UI frameworks (angular, react, svelte and vanilla typescript) as well as a data and index file. The structure looks like:

├── data.ts
├── index.tsx
├── your-example.component.html # ┓
├── your-example.component.ts # ┠ angular
├── your-example.module.ts # ┛
├── your-example.svelte # svelte
├── your-example.ts # typescript
├── your-example.tsx # react

What to include in index.tsx

All example index files look roughly the same, you will just need to fill in the highlighted lines. You can copy and paste the following:

/* eslint-disable import/no-unresolved, import/no-webpack-loader-syntax, @typescript-eslint/no-var-requires */
import React from 'react'
import BrowserOnly from '@docusaurus/BrowserOnly'
import { Example } from '@site/src/types/example'

const pathname = ''
const example: Example = {
component: () => <BrowserOnly>{() => {
// eslint-disable-next-line @typescript-eslint/naming-convention
const Component = require(`./${pathname}.tsx`).default
return <Component />
title: '',
description: <div></div>,
codeReact: require(`!!raw-loader!./${pathname}.tsx`).default,
codeTs: require(`!!raw-loader!./${pathname}.ts`).default,
codeAngular: {
html: require(`!!raw-loader!./${pathname}.component.html`).default,
component: require(`!!raw-loader!./${pathname}.component.ts`).default,
module: require(`!!raw-loader!./${pathname}.module.ts`).default,
codeSvelte: require(`!!raw-loader!./${pathname}.svelte`).default,
data: require('!!raw-loader!./data').default,
preview: require(`../_previews/${pathname}.png`).default,
previewDark: require(`../_previews/${pathname}-dark.png`).default,

export default example
  • pathname should correspond to your directory name
  • title should reference the library component(s) your using
  • description should be a brief description of your visualization with any data sources cited

Testing each framework

Before you submit a pull request, be sure you have verified that the example works for each framework on your local machine. In the packages/website directory, you can view your example by following the steps below:


  1. Run the command
    npm run start
  2. Open localhost:9300 and navigate to your example's page


Same steps above, but add &ts to the end of the url.


  1. Add your example's svelte file path to the imports array in src-demo/svelte-gallery.svelte
  2. From the terminal, run the command
npm run gallery:svelte


  1. Add your example's vue file path to the imports array in src-demo/App.vue
  2. From the terminal, run the command
npm run gallery:vue


  1. Import your angular module in gallery/src/main.ts
  2. Add the imported module to the imports field in the NgModule decorator:
    declarations: [AppComponent],
    imports: [... /* your angular module here */],
    bootstrap: [AppComponent],
    providers: [BrowserModule],
  3. Add the example component's selector to the Component decorator's template field:
    selector: 'app-component',
    template: `
    <!-- your angular selector -->
  4. From the terminal, run the command
    npm run gallery:angular
