Register new chart type

How to register new chart type from the community? I installed the new chart type package and tried to register it like this but still got the error.

import './bootstrap';
import Chart from 'chart.js/auto';
import {TreemapController, TreemapElement} from 'chartjs-chart-treemap';

Chart.register(TreemapController, TreemapElement);

import './bootstrap';
import Chart from 'chart.js/auto';
import {TreemapController, TreemapElement} from 'chartjs-chart-treemap';

Chart.register(TreemapController, TreemapElement);

Uncaught Error: "treemap" is not a registered controller.

Uncaught Error: "treemap" is not a registered controller.

I think because I register to the wrong one, not the chart object Filament is using to render chart, but I don't know how to get the right one.

I have a vey similar challenge, as I want to register a chartjs plugin.

import { Chart } from 'chart.js';
import annotationPlugin from 'chartjs-plugin-annotation';

Chart.register(annotationPlugin);

import { Chart } from 'chart.js';
import annotationPlugin from 'chartjs-plugin-annotation';

Chart.register(annotationPlugin);

@Mads Møller i have to copy the chart.js file in vendor, add the register code, then build it with esbuild, then use filament asset to publish it to public folder 1. install chartjs and plugin via npm 2. copy vendor/filament/widgets/resources/js/components/chart.js to resources/js folder 3. follow these steps: https://filamentphp.com/docs/3.x/support/assets#asynchronous-alpinejs-components 4. copy vendor/filament/widgets/resources/views/chart-widget.blade.php to resources/views/vendor/filament-widgets/chart-widget.blade.php 5. replace line 38 with ax-load-src="{{ \Filament\Support\Facades\FilamentAsset::getAlpineComponentSrc('chartjs') }}"
