This example displays the 113th U.S. Congressional districts as an interactive choropleth map, with each district shading orange on hover over a gray base. It uses a custom Albers USA projection via `d3.geo.albersUsa()` and renders SVG paths with `d3.geo.path`. District and state boundaries are drawn as white strokes using `topojson.mesh`, while district features come from `topojson.feature` on data fetched from GitHub-hosted JSON files. The visualization clips all paths to the landmass using a clip path derived from a US TopoJSON mesh.

Neighboring Congressional Districts

This example visualizes neighboring congressional districts from the 113th congress, highlighting the hovered district in red and its adjacent districts in orange. It uses topojson.neighbors to detect shared edges between district geometries. The map is rendered with d3.geo.path and an Albers USA projection, displaying district and state borders as white meshes. Hovering triggers a mouseover event that classifies neighboring districts via d3.selectAll, while the underlying geographic data comes from two TopoJSON files.

Congressional District Topology

This example visualizes the adjacency graph of U.S. congressional districts from the 113th Congress, drawing a node-link diagram atop a faded map of the country. District centroids serve as nodes, with edges connecting neighboring districts; districts off the map are excluded, and only links between earlier and later features are drawn. Built with d3.v3, the map uses d3.geo.albersUsa projection and d3.geo.path for rendering, while topological relationships are computed via topojson.neighbors and topojson.feature. The final graph is drawn as an SVG path, merging neighbor pairs with d3.merge.

Choropleth Map

A choropleth map of United States states renders geographic boundaries as SVG paths, colored light blue with black outlines and a red hover state. The map uses the topojson library to convert US Atlas TopoJSON data into GeoJSON features, then projects them with d3.geoAlbersUsa and renders them via d3.geoPath. Interactive zooming is enabled through a d3.zoom event that applies transform updates to the map group, while a categorical color legend displays the domain. State data loads from a remote US Atlas JSON file.

Albers Projection

This example displays a map of the United States using the Albers projection, with each state drawn as a filled gray polygon with white outlines. The visualization loads GeoJSON data from a remote `us.json` file via `d3.json`, which is then converted into SVG paths using `topojson.feature` and `d3.geo.path()`. The map is rendered as a single SVG path element within a 960×500 canvas, demonstrating a basic static choropleth without additional interactivity or styling layers.

US MAP

This interactive visualization displays a choropleth-style map of the United States, rendered as an SVG using React and D3 v5. The map shows state boundaries through purple interior lines, with land areas filled in green against a dark blue sphere background. The code employs `d3.geoAlbers` for the Albers equal-area projection, `d3.geoPath` to generate SVG paths, and `d3.geoGraticule` for grid lines. Geographic data comes from the `us-atlas` TopoJSON file, processed through `feature` and `mesh` from topojson library.

Let's make a map with D3.js!

This visualization displays U.S. states as a choropleth map, highlighting a subset of selected state IDs in orange while rendering all others in gray. It uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to draw SVG paths from TopoJSON data loaded from `us-10m.v1.json`. The code filters state features against a predefined set and applies the `.selected` CSS class, though the commented-out section means the highlighting is not rendered in the final output.

US State Map

This example displays a choropleth-style map of the United States, showing state boundaries as gray filled polygons with white strokes on a blank background. It uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to render the geographic shapes, while the TopoJSON `feature` API extracts state geometries from the `counties-10m.json` dataset hosted via jsdelivr. The map is drawn as SVG paths appended to a fixed 960×500 canvas, with styling applied through a CSS class.

A choropleth-style map of the United States renders state boundaries as black outlines on a white background, using an Albers USA projection centered within a 700x580 SVG. The visualization loads geographic features from a local `us-states.json` file and draws each state path via D3 v4’s `d3.geoPath` with a `d3.geoAlbersUsa` projection. No data values or color encoding are applied, leaving the map purely as a geometric outline of the country’s administrative divisions.
