Is it possible to create a multi level (stacked) donut chart with variable diameter on the last stack

Question

Is it possible to create a spider chart or sunburst or stacked doughnut chart in Highcharts or another charting library that has fixed width on the outer level and variable length similar to this one:

To confirm, I need to indicate the last data set visually by length so if one bar is 5 a and one is 10 then the second bar is twice as long.

Answer 1

That chart type is not supported by default in Highcharts, but you can combine two charts: column series in polar chart and sunburst:

Highcharts.chart('container', {
    chart: {
        polar: true,
        type: 'column',
        ...
    },
    ...
});


Highcharts.chart('container2', {
    chart: {
        type: "sunburst",
        ...
    },
    ...
});
