A Pie chart can be added to Spread, and the chart style can be changed using the chart API. The pie chart can only display one group of data, so use the chart.series().get() function to get the series information. Pie charts show the size of items in one data series, and the data points are shown as a percentage of the whole pie.
A Doughnut chart can be added to Spread, and the chart style can be changed using the chart API. The doughnut chart can display all series, with each shown as a ring that represents a data series.
