Convert GeoJSON objects to TopoJSON topology and quantize it to increase quality.

The topo_server module provides tools for converting GeoJSON to TopoJSON. See How to Infer Topology for details on how the topology is constructed.

See shapefile for converting ESRI shapefiles to GeoJSON, ndjson-cli for manipulating newline-delimited JSON streams, d3-geo-projection for manipulating GeoJSON, and topo_client for manipulating TopoJSON and converting it back to GeoJSON. See also us-atlas and world-atlas for pre-built TopoJSON.
