Data Charts support treemap type. To use the Treemap Chart, you can set the data chart type to GC.Spread.Sheets.DataCharts.DataChartType.treemap.
For example, you can insert a treemap data chart and configure the data chart by method setChartConfig.
Notes: before using the data chart, tables in data manager should be initialized.
