topojson-client

This provides tools for manipulating TopoJSON, such as to merge shapes or quantize coordinates, and for converting back to GeoJSON for rendering with standard tools such as d3.geoPath. topo2geo Converts one or more TopoJSON objects from an input topology to one or more GeoJSON features. topomerge Merges polygons (or meshes lines) from the specified source TopoJSON geometry collection object, assigning to the target object. topoquantize Quantizes the coordinates of the input TopoJSON topology and delta-encodes the topology’s arcs. See also topojson-server and topojson-simplify.
