Tooltip is used to display details about the items in the TreeMap. When space constraints prevent us from displaying the information using Data Labels, the tooltip comes in handy.
The tooltip is not visible by default, to make it visible, set the visible property in the tooltipSettings to true and injecting the TreeMapTooltip module.

ReactDOM.render(<App />, document.getElementById('treemap'));The tooltip content is displayed by default based on the weightValuePath. In addition, to show more information in the tooltip, use the format property and define field from the data source as ${datafield}.

ReactDOM.render(<App />, document.getElementById('treemap'));Tooltip can be rendered as a custom component using the template property in the tooltipSettings which accepts one or more UI elements as an input, that can be rendered as a part of the tooltip rendering. You can use ${datafield} as placeholder in HTML element to display the values from data source.
