Alternatively, you can generate it in vanilla JS in a webpage:

function make_gantt_chart(task_data) {
  let p = Plot.plot({
      width: 900,
      height: 500,
      y: { domain: ["D Job", "P Job", "E Job", "A Job", "N Job"] },
      marks: [
        Plot.barX(task_data, {
          x1: "startDate",
          x2: "endDate",
          y: "taskName",
          rx: 5,
          fill: function (d) {
            if (d.status == "RUNNING") {
              return "#669900";
            } else if (d.status == "FAILED") {
              return "#CC0000";
            } else if (d.status == "KILLED") {

            }
          }
        }),
        Plot.ruleY(["N Job"]),
        Plot.ruleX([d3.min(tasks.map((t) => t.startDate))])
      ]
    });

    d3.select(p)
      .select('g[aria-label="rule"]')
      .attr("transform", `translate(0,${p.scale("y").bandwidth})`);    
   d3.select('#container').append(() => p)
