This sample depicts the gold medal categories of the 2016 U.S. Summer Olympics. Each category is denoted with label template.
In this example, you can see how to place custom HTML templates in the
TreeMap items. The default text of the labels also have been
formatted.
Tooltip is enabled in this example. To see the tooltip in action,
hover the mouse over an item or tap an item in touch enabled devices.
Injecting Module
TreeMap component features are segregated into individual feature-wise
modules. To use a tooltip, inject the Tooltip module
using the TreeMap.Inject(TreeMapTooltip) method.
