USA Map

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.

USA Map

This interactive SVG map of the United States displays the 50 states colored purple, darkening to a lighter shade on hover. The visualization is built with React and D3.js, using the `geoAlbersUsaTerritories` projection and `d3.geoPath` to render geographic shapes from a TopoJSON file sourced from `us-atlas`. State interiors are drawn with a black stroke, and the data is loaded asynchronously using D3's `json` function and TopoJSON's `feature` and `mesh` utilities.

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.

USA Country Map

This map of the United States displays all 50 states using a pink fill with white boundaries, and hover interactions change each state’s color to purple. It is rendered as an SVG via React, using D3’s `geoPath` with the `geoAlbersUsaTerritories` projection. Geographic data for state land and interiors is loaded from a TopoJSON file using `useData`, `json`, and TopoJSON’s `feature` and `mesh`. The code imports `d3` and `topojson` packages within a React functional component.

USA Country Map

This USA country map visualizes the fifty states and their internal borders using the geoAlbersUsaTerritories projection from the `geo-albers-usa-territories` package, with geographic data loaded from the `us-atlas` TopoJSON source. The React-based app fetches the topology via `useEffect` and `d3.json`, then passes land features and interior state boundaries as props to a marks component. Rendering uses `d3.geoPath` to convert GeoJSON into SVG paths, with land areas filled teal and state boundaries stroked in black, while a CSS hover effect highlights individual states. The visualization is built with D3 v5, React 16, and TopoJSON.

USA Country Map

This choropleth-style map displays the 50 United States using an Albers equal-area conic projection, with each state filled in green and white borders defining state boundaries. Hovering over a state changes its fill to orange. The visualization is built with React, D3.js v5, and TopoJSON, using `d3.geoPath()` to render geographic shapes and the `geoAlbersUsaTerritories()` projection. State geometry is loaded from a US Atlas TopoJSON file, and the map is rendered as SVG.

USA country map

This example displays a map of the 50 U.S. states, with each state filled in navy and black borders outlining state boundaries. Hovering over a state changes its fill color to purple. The visualization uses React for component structure and D3’s `geoPath` with the `geoAlbersUsaTerritories` projection to render geographic data as SVG paths. TopoJSON data from the `us-atlas` package is processed via `feature` and `mesh` functions to generate the land and interior boundaries.

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.
