Fixed output

	const numPoints = 100
	data := make([]opts.LineData, numPoints)
	for ii := range 100 {
		theta := (float64(ii) / numPoints) * 360.0
		r := 5 * (1.0 + math.Sin((theta/180)*math.Pi))
		data[ii] = opts.LineData{Value: []float64{r, theta}}
	}

	polar := charts.NewLine()
	polar.SetGlobalOptions(
		charts.WithPolarOps(opts.Polar{}),
		charts.WithTitleOpts(opts.Title{Title: "Two Value-Axes in Polar"}),
		charts.WithTooltipOpts(
			opts.Tooltip{
				Show:        opts.Bool(true),
				Trigger:     "axis",
				AxisPointer: &opts.AxisPointer{Type: "cross"},
			}),
		charts.WithAngleAxisOps(opts.AngleAxis{
			PolarAxisBase: opts.PolarAxisBase{
				Type:       "value",
				StartAngle: 0.0,
			},
		}),
		charts.WithRadiusAxisOps(opts.RadiusAxis{}),
	)
	polar.AddSeries(
		"line", data, charts.WithCoordinateSystem("polar"),
	)

	os.WriteFile("Is-414.html", polar.RenderContent(), 0o644)

TODO: remove the EnablePolarType in bar chart.
