USA Map Visualization

USA Map

This visualization shows a map of the United States with state boundaries, rendered as SVG using React components. The map displays land areas in tan, state borders in black, and a light blue sphere background. The code uses d3.geoAlbers for the projection, d3.geoPath to generate paths, and d3.geoGraticule for grid lines, though graticules are defined but not rendered. Data comes from the us-atlas TopoJSON file, processed with topojson.feature for the nation outline and topojson.mesh for state interiors.

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.

This example displays a choropleth-style map of the United States, showing state boundaries and land areas in light green with black interior borders. It uses React to render an SVG, with D3's `geoPath` and the `geoAlbersUsaTerritories` projection from the `geo-albers-usa-territories` library. TopoJSON data is loaded from a remote URL, and the `feature` and `mesh` APIs extract land and interior boundaries for drawing. The visualization focuses on geographic shape rather than additional quantitative data.

Country Map of USA

This example displays a choropleth-style map of the United States, with each state filled in red and state boundaries drawn as black lines, using an SVG rendering. The map relies on D3’s `geoPath` and the `geoAlbersUsaTerritories` projection to render geographic features from TopoJSON data loaded via `topojson.feature` and `topojson.mesh`. React manages the component state through the `useData` hook, while CSS hover effects change a state’s fill color to blue. The data source is the `us-atlas@3.0.0` states-10m.json file.

This visualization displays a choropleth map of the United States, coloring each state in red with thin black internal borders. The map is rendered using React and D3 v5, with geographic shapes generated through `d3.geoAlbers` projection and `d3.geoPath`. State boundaries come from the US Atlas TopoJSON dataset, processed via `topojson.feature` and `topojson.mesh`. The SVG paths change to sky blue on hover using CSS, providing simple interactivity.

USA Country Map

This example displays a choropleth-style map of the 50 U.S. states, with each state filled in sky blue and separated by black borders. The visualization shows the geographic boundaries of the states, and hovering over a state highlights it in a warm orange color. The map is rendered as an SVG using React, with D3’s `d3.geoPath` and the `geoAlbersUsaTerritories` projection to convert TopoJSON data from the `us-atlas` package into drawable paths. The geometric data is loaded via `d3.json`, and state boundaries are computed using TopoJSON’s `feature` and `mesh` functions.

USA Country Map

This example renders a choropleth-style USA map using SVG, showing state boundaries and filled land areas in orange. It uses D3’s `geoPath` and the `geo-albers-usa-territories` projection, with React managing the component structure. TopoJSON data is loaded via `d3.json`, and state outlines are drawn using `feature` and `mesh` from the `topojson` library. The map highlights territorial inclusion through the custom projection, while the `styles.css` defines the land fill and interior stroke.

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.
