## Usage
Mindmap is an appropriate layout method for tree data structure. Please use it with TreeGraph. As the demo below, you can deploy it in `layout` while instantiating Graph.
You can set different configurations for different nodes if the parameter is Function type. Please refer to the ducuments for more information.
