This visualization displays the boundaries of every county in the United States, along with state lines and a stylized national outline with a drop-shadow effect. The map uses an Albers equal-area conic projection via `d3.geoAlbersUsa()` and renders GeoJSON paths with `d3.geoPath()`. It employs the TopoJSON client to convert TopoJSON data from a GitHub-hosted file into features, and uses SVG elements with blur filters for the shadow.

US Counties

This map of US counties displays all county boundaries with a subtle drop-shadow effect. The code uses D3 v4’s `d3.geoAlbersUsa` projection and `d3.geoPath` to render geographic features. It loads TopoJSON from a local `counties.json` file and converts it to GeoJSON via `topojson.feature` and `topojson.mesh`. The visualization plots state borders as a separate mesh, overlays white and blurred nation outlines for depth, and draws each county as an outlined SVG path with thin gray strokes.

US Counties

This example shows a map of all US counties and state boundaries, rendered with a drop-shadow effect for visual depth. It displays the nation’s outline, state lines, and individual county borders using SVG paths. The code uses D3 v4’s `d3.geoAlbersUsa()` projection and `d3.geoPath` to draw the geography, while TopoJSON’s `topojson.feature`, `topojson.merge`, and `topojson.mesh` convert the county data from the provided JSON. A blurred filter and layered `use` elements create the shadow effect.

US Counties

This example displays a choropleth map of every county in the United States, using the USCounties.json TopoJSON file from the gist repository by NPashaP. It shows the geographic boundaries and locations of each county, including territories like Aleutians East Borough in Alaska and Charlottesville city in Virginia. The visualization is rendered using the d3.geoPath API to project and draw the TopoJSON topology onto a canvas, with the d3.forceSimulation or similar force-directed layout not applied here—instead, the arcs and polygons are directly encoded into paths. The map relies on the geometry collection and property data (GEOID10, NAMELSAD10, INTPTLAT10, INTPTLON10) to place each county accurately.

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.

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.

map: usa, counties

This example renders a choropleth-style map of the United States, displaying county and state boundaries overlaid on landmasses, with graticules and a sphere outline. It uses a React component with `d3.geoAlbersUsa` for projection and `d3.geoPath` for drawing geometries. Data comes from the US Atlas TopoJSON (`us-atlas@3.0.0/counties-10m.json`), processed with `topojson.feature` and `topojson.mesh`. Interactive tooltips show county and state names on hover. The SVG output is styled with semi-transparent fills and distinctive boundary strokes.

Country Map

This example renders a choropleth-style map of United States counties on an SVG canvas. Each county polygon is drawn as a purple path with white strokes, and hovered counties turn red, with the county name appearing as a tooltip. The visualization uses D3 v5’s `geoAlbersUsa` projection with `geoPath` to generate the shapes, and TopoJSON’s `feature` method to parse county boundaries from the us-atlas dataset. County names come from the TopoJSON properties, while the map loads via a remote JSON URL.
