Title
Does the tree diagram support the style when configuring hover?
Description
Can the tree diagram update the style of the selected state (enlarge, add borders)?
Solution
In vchart, the state of selection or mouse hover can be configured by the primitive state. For your needs, you can configure different styles on state.selected on the leaf primitive. For example, if you need to modify the color, you can configure fill or fillOpacity; if you need to configure the border, you can configure stroke or lineWidth; if you need to configure the magnification effect, you can configure scaleX, scaleY, and scaleCenter.
