US State Map

Country Map

This example displays a choropleth map of the 50 US states, rendered as SVG paths with a blue fill and black state borders. The visualization uses the `geoAlbersUsaTerritories()` projection and `d3.geoPath()` to draw geographic features, while `useData` fetches TopoJSON data from the `us-atlas` package. State boundaries are generated via the `feature()` and `mesh()` functions from TopoJSON, and hovering highlights a state blue.

US State Map

This example displays a static map of US states, with each state rendered as a gray path using an SVG. The code loads state boundary data from a TopoJSON file and converts it into GeoJSON features using the `feature` function from topojson. It then projects the geographic coordinates to screen space with the `geoAlbersUsa` projection and `geoPath` generator from D3, appending the resulting paths to the SVG. No additional data or interactivity is applied.

US Country Map

This example displays a static choropleth map of the United States, with all states uniformly filled in red on a light yellow background. Using D3 v4 and TopoJSON, it loads state boundaries from the `us-atlas` dataset and renders them as SVG paths with `d3.geoPath` and the `d3.geoAlbersUsa` projection, which automatically positions Alaska and Hawaii. The code applies stroke styling to delineate state borders, offering a simple baseline for geographic data visualization.

Country Map

This example shows a choropleth map of the United States, with each state rendered as a green SVG path on a light blue background. It loads US state boundaries from the us-atlas TopoJSON file and uses the `d3.geoPath` projection with `d3.geoAlbersUsa` to create the map. The code relies on `d3.json` to fetch the data and the `topojson-client` library to convert TopoJSON features into GeoJSON paths for rendering.

USA country map

This example displays a choropleth-style map of the 50 US states, rendered as navy SVG paths with black state borders. The map uses the `geoAlbersUsaTerritories` projection and `d3.geoPath` to draw geographic features from TopoJSON data loaded via `d3.json` from the us-atlas package. State shapes highlight in purple on hover, with React managing the component state and rendering the SVG output.

USA Country Map

This choropleth-style map displays the contiguous United States rendered as an SVG, with each state filled in maroon and state boundaries drawn in black. The visualization uses a React component with the `geoAlbersUsaTerritories` projection and `d3.geoPath` to draw the geographic features. State boundaries are created using TopoJSON’s `mesh` function, while the underlying data comes from a remote TopoJSON file served via a GitHub gist. The map is static with no interaction or animation.

Country Map

This example displays a choropleth-style map of the United States, with each state rendered as a green filled path and internal borders drawn in teal. It uses the `geoAlbersUsaTerritories` projection from the `geo-albers-usa-territories` package to show all states including territories. The geographic data comes from the `us-atlas` TopoJSON file, processed through TopoJSON’s `feature` and `mesh` functions. The visualization is built with React and D3’s `geoPath`, rendering purely as SVG elements within a 960x500 viewport.

US Map

This example displays a map of the 50 US states, with each state filled in red and white borders separating them. The visualization uses the `geoAlbersUsaTerritories` projection and the `d3.geoPath` API to render geographic shapes as SVG paths. The map is generated from TopoJSON data loaded from a remote US atlas source, and it enhances interactivity by changing each state’s color to green when the pointer hovers over it.
