public final class GeoUtils
extends Object
```
Utility to manage TopoJson definitions.
TopoJson is an extension of GeoJSON that encodes topology.
Rather than representing geometries discretely, geometries in TopoJson files are stitched together from shared line segments called arc.
PAY ATTENTION CHARBA doesn't include any TopoJSON files itself.
