GraphNodeViewBehavior class

Controls how nodes are rendered and how they interact with user input.

This class manages node visualization and interaction through a combination of a custom widget builder, tooltip behavior, and an optional child widget. It provides control over the visual representation of nodes and their response to user interactions.

Use GraphNodeViewBehavior.defaultBehavior for standard node rendering with configurable tooltip options and node styles. For custom node rendering, provide your own builder function.
