arcWidths property
Fixed width of the arcs for each of the ring drawn in the sunburst. The arcs will be drawn exactly as the defined width, any part exceeding the chart area will not be drawn. If the maxDisplayLevel to be rendered is greater than the arcWidths provided, the last value of the arcWidths will be used to fill the rest of the levels. arcWidths has more precedence than arcRatios. If neither arcRatios nor arcWidths is provided, space will be distributed evenly between levels.
