I have a topojson file of all US states that I would like to merge into a single entity, i.e. removing common arcs.
Several answers suggest using topojson.mesh(), as is pointed out in the answer here: D3: Merge interior svg paths?
However I would like to save the output topojson for reuse in the future. So is there a way to manipulate the original file through the command line tool instead?
Thanks
