NonOverlappingRect

import { NonOverlappingRect, NonOverlappingRectGroup } from 'cx/svg';

The NonOverlappingRect and NonOverlappingRectGroup widgets are commonly used for hiding excessive chart labels. In the following chart, labels which are overlapping other labels are hidden. Try dragging markers around and see how it behaves.
