TreeMapChart drill down

The TreeMap chart enables users to navigate through layers of data, uncovering details.
This feature ensures that users can easily track their position within the data hierarchy and navigate back to broader overviews without losing context, with the help of navigation paths at the top of the chart.

Additionally, you can disable the drill-down feature or limit the number of visible node levels:

// Show only 1 level of child nodes
chart.setDisplayedLevelsCount(1)

// Disable drill-down interaction
chart.setDrillDownEnabled(false)
