This graph displays the topology of U.S. counties, with each node positioned at its county centroid and links connecting neighboring counties that share a border. The visualization uses TopoJSON’s `topojson.neighbors` to identify adjacent counties and `d3.geoPath` to compute centroids from simplified geometry. A background map and white county mesh provide geographic context, while black lines trace the adjacency network. The code loads data from the us-10m.v1.json file and renders entirely in SVG using D3 v4.

AI-generated description

This graph shows the topology of U.S. counties. Each node in the graph represents a county, positioned at the county centroid, while each link represents two neighboring counties sharing a border. (This graph is only approximate, as it is based on simplified geometry.)
