This choropleth displays the 50 U.S. states with land areas filled in green and white state borders, highlighting a state in orange on hover. It uses React and D3 v5’s `geoPath` with the `geoAlbersUsaTerritories` projection to render geographic features as SVG, pulled from TopoJSON data in the US Atlas (`states-10m.json`). The `feature` and `mesh` functions from TopoJSON extract land polygons and interior boundaries, which are styled via CSS.

This example displays a choropleth-style map of the United States using SVG paths. It renders state boundaries and fills each state as a separate path, with a hover effect that turns states red via CSS. The visualization loads TopoJSON data from a remote URL and converts it to GeoJSON using the `topojson.feature` and `topojson.mesh` APIs. It relies on `d3.geoPath` to project and draw the geographic shapes, while `d3.json` fetches the data asynchronously. State borders are drawn as a white stroke overlay for visual separation.

USA Country Map

This visualization displays a choropleth map of the 50 US states using a green fill, with white state borders and a purple hover highlight for individual states. It renders geographic data from a TopoJSON file using React and D3's `geoPath` with the `geoAlbersUsaTerritories` projection. The `feature` and `mesh` functions from TopoJSON extract land and interior boundary data, which are drawn as SVG paths within a React component.

Country Map

This visualization displays the 50 U.S. states as an interactive choropleth map, rendered in SVG within a React framework. It uses d3.geoPath with the geoAlbersUsaTerritories projection to draw state boundaries, with state fills in steelblue that turn white on hover. Geographic data comes from a TopoJSON file loaded via d3.json, and borders are derived using TopoJSON’s feature() and mesh() functions.

This example displays a map of the United States with individual state boundaries rendered as SVG paths. The visualization uses TopoJSON data from the us-10m dataset, with states drawn via d3.geoPath and state borders emphasized with a white stroke. The code employs the D3 v4 library and topojson.feature to extract state geometries, while a CSS hover effect turns states red for interactive feedback. The rendering is purely SVG-based within a React framework.

Fork of USA Country Map

This choropleth displays the 50 U.S. states, each filled in green with white interior borders, and highlights states in orange on hover. It uses a geospatial projection via `geoAlbersUsaTerritories()` and renders the map with `d3.geoPath` on an SVG canvas. State boundaries come from the US Atlas TopoJSON dataset, which is loaded with `d3.json` and processed through TopoJSON’s `feature` and `mesh` functions. The React app manages data loading with `useState` and `useEffect` hooks.

This interactive map of the United States uses a D3.js geographic projection to display state boundaries, rendered as SVG paths from TopoJSON data. Clicking a state zooms in via a smooth `transition` that adjusts the group’s scale and translate attributes, while the clicked state is highlighted in orange. A click on the background resets the view, returning the map to its original scale and stroke width. The example relies on `d3.geo.albersUsa`, `d3.geo.path`, and TopoJSON’s `feature` and `mesh` methods.

Fork of USA Country Map

This example displays a choropleth-style map of the 50 US states, rendered as an SVG where each state boundary is drawn using D3’s `geoPath` and a custom `geoAlbersUsaTerritories` projection. The map initially fills each state with a teal color, and hovering over a state highlights it in magenta. Data is loaded asynchronously from the US Atlas TopoJSON file (`states-10m.json`) using React hooks (`useState`, `useEffect`) and processed with TopoJSON’s `feature` and `mesh` functions to generate land and interior borders. The visualization is built with React 16 and D3 v5, with styling defined in an external CSS file.

USA Map

This example displays a choropleth-style map of the 50 US states using the `geoAlbersUsaTerritories` projection from the `geo-albers-usa-territories` library. The visualization renders geographic data from `us-atlas@3.0.0` TopoJSON via `d3.geoPath` within a React component, using `feature()` and `mesh()` from `topojson` to generate land and interior boundaries. States are filled with a yellow color and outlined in black, while hovering on a state highlights it in green, as defined in the accompanying CSS. The map is drawn as SVG at 960×600 resolution, with a loading state displayed until data is fetched.
