Some of these files are from the us-atlas:

make topo/us-10m.json
- us-congress-113.json -
make topo/us-congress-10m.json
Others are from the world-atlas:

@mbostock. I'm curious whether the source US Census Bureau file for us.json included both counties and states or just counties. I have created a topoJSON file for school districts in the US (https://github.com/CenterForAssessment/SGPspatialData/blob/master/Shape_Files/Topojson_2016/USA_Districts.json) but it doesn't include state outlines (just district). National maps with thicker state boundaries look nicer. The national map of school districts is built using ogr2ogr -append -update with individual state files. Is there a way to build the state boundaries as parting of this merge process?
