This interactive map displays all U.S. counties as gray polygons with state borders overlaid in white. Clicking a state zooms in on that region, while clicking a county triggers a deeper zoom to a scale of 23, with another click resetting the view. The visualization uses D3 v3 and TopoJSON to load geographic data from a gist, projecting it with `d3.geo.albersUsa` and rendering paths via `d3.geo.path`. Transitions animate the zoom using SVG transform scaling and translation, with hover effects highlighting counties and states in orange.

Zoom in Map Demo

Clicking a US state zooms to that state at 4× magnification, while clicking again resets the view. Clicking an individual county zooms in much deeper, to 23×, centering on that county. Built with D3 v3 and TopoJSON, the map renders US states and counties as SVG paths using an Albers USA projection, with smooth 750-millisecond transitions handled by D3's `transition` and `attr` methods. The data comes from a raw GitHub gist containing US TopoJSON topology.

US Counties

This map of US counties displays all county boundaries with a subtle drop-shadow effect. The code uses D3 v4’s `d3.geoAlbersUsa` projection and `d3.geoPath` to render geographic features. It loads TopoJSON from a local `counties.json` file and converts it to GeoJSON via `topojson.feature` and `topojson.mesh`. The visualization plots state borders as a separate mesh, overlays white and blurred nation outlines for depth, and draws each county as an outlined SVG path with thin gray strokes.

Untitled

This example displays a map of New York counties using an Albers USA projection with D3 v3 and TopoJSON, showing county boundaries and state borders in white. Clicking a county triggers a smooth zoom animation that centers the view on that region, highlighting it in sky blue while scaling stroke widths inversely. The visualization uses `d3.geo.albersUsa`, `d3.geo.path`, and a 750-millisecond transition with the `scale` and `translate` transforms, with data loaded from a GitHub-hosted TopoJSON file.

country map

This visualization displays a map of the United States at the county level, using a green fill with black borders that highlight individual county boundaries. Hovering over any county changes its fill color to yellow. The map is rendered as SVG using D3 v5, with geographic projections handled by `d3.geoAlbersUsa` and `d3.geoPath`. County boundaries are generated from TopoJSON data loaded from the us-atlas package, and the code relies on `topojson.feature` to extract geographic features and `topojson.mesh` for boundary calculations.

US Map

This interactive visualization displays all US counties as a choropleth-style map rendered with a natural Earth projection using d3.geoPath. The map is drawn with SVG elements, featuring graticules and a sphere outline to provide geographic context. County boundaries come from a TopoJSON file loaded asynchronously and converted to GeoJSON features. Built with React and D3 v7, the visualization dynamically fills the browser window and uses the Poppins font for its minimal interface.

Zoom to Bounding Box II

This example demonstrates smooth zooming and panning over a map of the United States using Albers equal-area projection. Users click individual states, triggering a 750-millisecond animated transition to a bounding box around that state, while the map remains freely navigable via mouse drag and wheel zoom. The visualization uses `d3.geo.albersUsa` for projection, `d3.behavior.zoom` for interactive and animated transformations, and `d3.geo.path` to render state boundaries and a mesh overlay from the US TopoJSON data file. Active states highlight in orange, and stroke widths adjust dynamically during zoom.

Let's make a map of US-counties with D3.js:"hover and county name "

This example displays an interactive map of U.S. counties rendered as SVG paths, with each county’s name appearing as a tooltip on hover. The map uses the `geoAlbersUsa` projection and `geoPath` from D3 v5, while TopoJSON’s `feature` method extracts county geometries from the us-atlas counties-10m.json dataset. Hovering highlights the county in green via a CSS `:hover` rule. The visualization depends on D3’s `select` and `json` utilities to fetch and bind the geographic data.

US Counties

This visualization displays the boundaries of every county in the United States, along with state lines and a stylized national outline with a drop-shadow effect. The map uses an Albers equal-area conic projection via `d3.geoAlbersUsa()` and renders GeoJSON paths with `d3.geoPath()`. It employs the TopoJSON client to convert TopoJSON data from a GitHub-hosted file into features, and uses SVG elements with blur filters for the shadow.
