Forked from 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 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 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.

Country Map

This interactive map visualizes the fifty United States using a pink fill for each state and black borders, with a hover effect that changes the fill color to purple. Built with React and D3 v5, it renders geographic data as SVG paths using `d3.geoPath()` with the `geoAlbersUsaTerritories` projection. The code loads US state boundaries from a TopoJSON file via `us-atlas@3.0.0`, applying `feature()` and `mesh()` from TopoJSON to extract land polygons and interior borders.

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 visualization displays the 50 U.S. states using a SVG map with land areas filled in olive and state borders in white. It uses the `geoAlbersUsaTerritories` projection and `d3.geoPath` to render geographic features from TopoJSON data sourced from the US Atlas. The map is built with React, employing the `useData` hook to asynchronously load and process the topology. Hovering over a state highlights it in orange, demonstrating interactive feedback.

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 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.

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.
