Highcharts Treemap
In this chapter we will introduce to you the heat map of Highcharts.
We have already learned about Highcharts configuration syntax in the previous chapters. Next let's look at other configurations of Highcharts.
Treemap
series configuration
Set the type attribute of series to treemap, and series.type describes the data column type. The default value is "line".
