This interactive map of the United States uses a linear color scale to visualize state-level data values, with states shaded from light blue to dark blue based on their associated values. The visualization loads CSV data containing state IDs and their corresponding quantitative values, then merges this with US state boundaries from a GeoJSON source. Built with D3 v6 and React, the map renders as an SVG using the `d3.geoPath` generator to draw state outlines, while the `topojson.feature` API extracts state features from the geographic data. States without matching CSV entries appear in gray.

USA Map

This choropleth map of the United States colors each state according to a numeric value loaded from a CSV file, using a linear lightred-to-red scale. The SVG rendering is built with d3.geoPath, which projects the US states from a GeoJSON file, while topojson.feature extracts the state features. State FIPS codes from the CSV are matched against the GeoJSON IDs to assign fills, with gray as the default for missing data. The visualization relies on d3.select, d3.csv, and d3.json for data loading.

USA Map

This visualization displays a choropleth map of the United States, where individual states are filled with varying intensities of red based on values loaded from a CSV file. States without matching data appear in gray. The map is rendered as an SVG using D3.js, with geographic boundaries drawn via `d3.geoPath` and TopoJSON features from the `us-10m.v1.json` dataset. A `d3.scaleLinear` maps data values to a color range from light red to deep red for each state's fill.

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 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.

USA state Map

A choropleth map of the United States colors states based on a numeric value from a CSV file, with a linear color scale mapping low values to light red and high values to dark red. The map is rendered as SVG using D3 v6 and topojson, with the `d3.geoPath` generator drawing state boundaries and `d3.scaleLinear` adjusting fill colors. States without matching data appear blue. The CSV is loaded via `d3.csv`, and state boundaries come from the us-10m.v1.json TopoJSON file.

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 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 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.
