The example draws a diagonal line across the bounding box of every U.S. county, creating a dense, cross-hatched pattern over the nation. Using `d3.geo.bounds`, it computes each county’s geographic extent and maps those bounds to projected coordinates via `d3.geo.path` with an Albers USA projection. The results are rendered as a single `MultiLineString` in SVG, built from TopoJSON county data. The visualization highlights the irregular shapes and varying sizes of county boundaries through the intersecting diagonals.
