I'm attempting to draw some contours on a chart with Plot.contour - for reasons I don't understand, fill: Plot.identity doesn't work (what is this?) - but fill: true does show the contours but without colouring by contour.

    color: {
      scheme: "Reds",
      domain: [0, 6],
    },
    marks: [
      Plot.contour(thermalData, {
        fill: true,
        x: "time",
        y: "altitude",
        value: "ti",
        stroke: "black",
        fillOpacity: 0.8,
      }),
