import { HeatMap } from "react-grid-heatmapjs";
import "react-grid-heatmapjs/dist/style.css";

  title: "Dummy Heat Map",
  colorRange: [
    {
      from: 0,
      to: 30,
      color: "#4074b3",
      name: "Cold",

      data: [10, 5, 50, 2, 25],
      total: 150,
    },
    {
      name: "Series 2",
      data: [1, 12, 50, 11, 18],
      total: 125,
    },
    {
      name: "Series 3",

      total: 175,
    },
  ],
  xaxis: {
    labels: ["Label 1", "Label 2", "Label 3", "Label 4", "Label 5"],
    totals: [30, 60, 90, 120, 150],
  },
};

<HeatMap
    title={data.title}
    colorRange={data.colorRange}
    series={data.series}
    xaxis={data.xaxis}
/>

The data above will produce this heatmap.
