This choropleth map colors US states by average annual sunshine hours, using a yellow-green sequential scale. The data is stored in a JavaScript Map for approximately 20 states, with missing states rendered pale green. Built with D3 v7 and topojson-client, it uses `d3.geoAlbersUsa()` for projection, `d3.geoPath()` for rendering state boundaries, and a custom tooltip on mouse events. The legend is drawn inside the SVG, and state data comes from the us-atlas states-10m GeoJSON.

Fork of country map

This fork of a country map visualizes average annual sunshine hours per U.S. state using a choropleth map. Hovering over a state reveals its exact yearly hours via a tooltip, with colors ranging from yellow to red based on a sequential scale. The visualization uses D3 v7’s `d3.geoPath` and `d3.geoAlbersUsa` projection to render TopoJSON state boundaries from the us-atlas dataset, while `d3.scaleSequential` and `d3.interpolateYlOrRd` handle color encoding. A linear gradient legend displays the hour range.

Fork of US states map : with colorScale. One color for each country

This choropleth map displays US states, each filled with a distinct color from a categorical palette. The visualization uses the D3.js library, specifically `d3.geoPath` with `geoAlbersUsa` projection, to render the map from a TopoJSON file loaded from the us-atlas package. The color scale assigns colors based on the state's name, and hovering over a state turns it green via CSS. The map also includes tooltips that reveal the state name using the `.append('title')` method.

Fork of US states map : with colorScale. One color for each country

A choropleth map of US states renders each state as a muted gray SVG path with thin dark borders, using an Albers USA projection. The visualization currently shows uncolored states, though the code defines a color scale with `d3.scaleOrdinal` and `schemeCategory10` for per-state coloring. Hovering any state turns it green via CSS. The map is built with `d3.geoPath`, TopoJSON state features, and the `geo-albers-usa-territories` projection, loading geographic data from the `us-atlas` package.

Fork of Fork of USA Country Map

A choropleth map of the United States shows each state as a filled, pink polygon with white interior boundaries, highlighting states on hover by turning them orange. Built with D3 v5, the visualization uses `geoAlbersUsaTerritories` for the projection and `geoPath` to render the geographic features. State boundaries come from the `us-atlas` TopoJSON file, processed via the TopoJSON library's `feature` and `mesh` functions, and displayed within a React application using SVG.

Fork of Country map

This choropleth displays all U.S. states as sky-blue filled polygons with teal borders marking state boundaries. Using the geo-albers-usa-territories projection via d3.geoPath, the map renders TopoJSON data from the us-atlas package. React manages the SVG output, while d3.geoGraticule and a mesh from topojson generate the underlying grid lines and interior state divisions.

Fork of Map

This example displays a choropleth-style map of the United States, with each state filled in a light blue shade and outlined by dark gray borders, over a pale background. Hovering over a state reveals its name via an SVG `<title>` tooltip. The visualization uses a `d3.geoAlbersUsa` projection and `d3.geoPath` to render TopoJSON data from the us-atlas package, drawing both individual state polygons and the national outline. State names are derived from the TopoJSON geometries’ `properties.name` field.
