This map of Virginia depicts the boundaries of all counties and independent cities, with a projected conic conformal projection. The visualization loads a TopoJSON file, `va-counties.json`, which contains the state outline, county borders, and city polygons. Using D3 v3 with the `d3.geo.path` and `d3.geo.conicConformal` APIs, the code first draws the state as a gray shape, then overlays white lines for county borders via `topojson.mesh`. The map is centered by calculating the bounds of the state and translating the projection accordingly.

Make with make topo/va-counties.json in the U.S. Atlas project.

U.S. Counties TopoJSON

This map displays the boundaries of every county in the United States using data from a TopoJSON file fetched from `https://d3js.org/us-10m.v1.json`. It renders the county shapes as filled SVG paths, with a white mesh overlay showing county borders via `topojson.mesh`. Hovering over any county turns it red. The visualization is built with D3 v4, using `d3.geoPath` to project the geometry and `topojson.feature` to extract the features, relying on the `us-atlas` TopoJSON data source.

County Topology

This graph shows the topology of U.S. counties as a network, where each node sits at a county centroid and links connect neighboring counties that share borders. The visualization uses simplified geometry from a TopoJSON file, rendering the nation and county boundaries as SVG paths via `d3.geoPath`. Node positions come from path centroids, while neighbor relationships derive from `topojson.neighbors` on the county geometries. Edges are drawn as straight lines between connected centroids, overlaid on the map to reveal adjacency patterns across the country.

County Topology

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.

Map D3

This map displays the counties of the United States using a natural Earth projection. The visualization draws each county as a separate SVG path, with white fill and black borders. The code loads TopoJSON data from a remote source, converts it to GeoJSON using the `topojson.feature` API, and renders it with `d3.geoPath` and `d3.geoNaturalEarth1`. It utilizes the D3 v5 library and appends all shapes within a single SVG container.

U.S. Counties TopoJSON Mesh

This example renders a minimalist map of U.S. counties using a TopoJSON mesh from the U.S. Census Bureau’s shapefile, served via the `us-10m.v1.json` file. The SVG visualization displays county boundaries as thin black lines with rounded joins, and overlays small circles at each arc’s starting point, revealing the topological structure of the data. The code uses `d3.geoPath` to project the mesh and `topojson.mesh` to extract boundaries, while `topojson.transform` positions the circles. Rendering is entirely SVG-based with D3 v4, and the map uses no fill, focusing purely on geometric outlines.

country map

This visualization displays a map of the United States at the county level, using a green fill with black borders that highlight individual county boundaries. Hovering over any county changes its fill color to yellow. The map is rendered as SVG using D3 v5, with geographic projections handled by `d3.geoAlbersUsa` and `d3.geoPath`. County boundaries are generated from TopoJSON data loaded from the us-atlas package, and the code relies on `topojson.feature` to extract geographic features and `topojson.mesh` for boundary calculations.

US Map

This interactive visualization displays all US counties as a choropleth-style map rendered with a natural Earth projection using d3.geoPath. The map is drawn with SVG elements, featuring graticules and a sphere outline to provide geographic context. County boundaries come from a TopoJSON file loaded asynchronously and converted to GeoJSON features. Built with React and D3 v7, the visualization dynamically fills the browser window and uses the Poppins font for its minimal interface.

Gist 5967514

This example displays a map of U.S. counties using a TopoJSON shapefile from the U.S. Census Bureau, rendered as gray-filled paths with white borders that turn red on hover. It shows the geographic boundaries of counties and responds to clicks, though the click behavior only logs to the console. The visualization uses D3 v3’s `d3.geo.path()` to project and draw the SVG paths, and TopoJSON’s `topojson.feature` to extract GeoJSON features from the topology. The map is static, with no zoom or pan, and the hover effect is the only interactive styling.
