This choropleth map of US states colors each state by its population, using a linear color scale from light blue to green. Hovering over a state highlights its borders and displays a tooltip with the state name and population count; invisible Voronoi cells derived from state centroids enable hover detection for small or island states. The visualization is built with D3, TopoJSON, and the geo-albers-usa-territories projection, using data from the us-atlas package and a GitHub-hosted population CSV.

Fork of Fork of US States with Hover

This choropleth map of US states uses a green color scale to encode population, with hover interactions highlighting states and displaying their name and population via a tooltip. Built with D3.js, it renders geographic features using `d3.geoPath` and a GeoAlbers USA projection, while `Delaunay` from D3 creates invisible Voronoi cells for reliable hover detection. Population data comes from a CSV of US Census Bureau estimates, and state shapes use US Atlas TopoJSON data.

Fork of Fork of US States with Hover

This interactive map of United States counties and states uses a Voronoi overlay to enable hover detection across the entire geographic area, including small islands. The visualization renders state boundaries with a white mesh and highlights the hovered state in dark gray with a black outline. Built with d3.geoPath, d3.geoCentroid, and Delaunay triangulation, it loads geographic data from the us-atlas TopoJSON source. Hovering over any state or invisible Voronoi cell triggers a mouseover event that updates the foreground highlight state.

Fork of US States with Hover

This fork of the US States map adds hover interactions using invisible Voronoi cells for precise detection, even over small islands. Built with D3 and topojson-client, it loads US Atlas topology from a CDN, renders state shapes via `d3.geoPath`, and highlights hovered states with a distinct fill and stroke. The map uses a memoized background layer and a foreground hovered-state layer, with a feature flag to optionally visualize the Voronoi overlay.

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 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.
