Grouped TreeMap (Vue)

The sample shows a grouped TreeMap using CollectionView.

The data binding for TreeMap is slightly different than FlexChart, and more similar to FlexPie.

The binding property is used to calculate the size of the node as compared to other node values. The property should contain numeric data.

The bindingName property is used to show name of the node. It should be an array or a string.

This example uses Vue.
