Heatmapjs React

A very simple port of heatmap.js for React. The idea behind this component is to be able to display a heatmap over any type of content (image, div, components ...). Inspired by react-heatmap.

import { Heatmap } from "@sarpere/heatmapjs-react";
const App = () => {
    const data = [{ x: 10, y: 15, value: 5}, { x: 50, y: 50, value: 2}, ...];
    return (
        <Heatmap max={5} data={data} />
    )
}
