StylingPolicy, VisualizationItem

All Known Implementing Classes:

ClusterStylingPolicy, SegmentsStylingPolicy
```
public interface ClassStylingPolicy
extends StylingPolicy
```
Styling policy that is based on classes, for example clusters or labels. This allows for certain optimizations such as marker reuse, and thus is preferred when possible.
