This example displays a map of the United States by rendering the nation’s outline and state boundaries as solid blue shapes on a large SVG canvas. It loads geographic data from the us-atlas TopoJSON file and converts it using the topojson.object API. The map is drawn with D3.js v3, using d3.geo.path with a Mercator projection to generate the SVG path data. The page relies on the d3.v3 library and topojson.v0 for data processing.

USA Country Map with Topojson data

This example displays a choropleth-style map of the United States, with each state rendered as a separate SVG path using a topojson dataset. It shows state boundaries and names via tooltips. The code uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to generate the paths, while `topojson.feature` converts the TopoJSON topology into GeoJSON features. The map is drawn with SVG elements, and the data is loaded asynchronously from a GitHub gist using D3’s `json` method.

USA Map with TOPO JSON Data

This example presents a stylized map of the United States, displaying state boundaries and land masses with distinct colors for spheres and geographic regions. The visualization renders as an SVG and uses React to manage the component lifecycle. It loads geographic data from the US Atlas TopoJSON, converting it with `topojson.feature` and `topojson.mesh`, then projects it using `d3.geoAlbers` and `d3.geoPath`. Graticules are included via `d3.geoGraticule`, though not explicitly drawn in the component.

USA Country Map with Topojson data

This map of the United States renders state boundaries using a yellow fill with blue outlines. The visualization employs D3’s `geoAlbersUsa` projection and `geoPath` to generate the SVG paths from TopoJSON data fetched from a GitHub gist. State names appear as tooltips via appended `title` elements, and hovering changes the fill color to green. The code uses `topojson.feature` to convert the TopoJSON topology into GeoJSON features, and relies on the `geo-albers-usa-territories` library for the projection. The SVG canvas is fixed at 960 by 500 pixels, with styling applied via an external CSS file.

USA Map Using TOPOJSON Data

A US map displays state boundaries as thin red lines over teal land masses, with a dark sphere background and graticule grid. The visualization uses `d3.geoPath` with a `geoAlbers` projection to render SVG paths from TopoJSON data loaded via `d3.json` from the US Atlas repository. React manages component state and rendering, while `topojson.feature` and `topojson.mesh` extract nation outlines and state interior borders. The map spans 1000 by 600 pixels, showing the contiguous states with visual emphasis on border delineation.

U.S. TopoJSON

This example displays a layered map of the United States using county, state, and national boundaries. The map is rendered as SVG, with counties stroked in thin gray, states in thin black, and the nation in a thicker black outline. It loads TopoJSON data from the us-atlas package and uses the topojson-client library to compute and draw the geographic meshes and features. The visualization is built with d3.v4, using d3.json for data fetching and d3.geoPath for path generation.

USA Map -Aishwarya M

This example displays a map of the United States on an orange background, rendered as a single green SVG path. It fetches world country boundaries from a TopoJSON file via `d3.json`, filters the data to the United States, and projects it using `d3.geoAlbersUsa` with `d3.geoPath`. The visualization uses D3 v5 and TopoJSON’s `feature` method to convert the TopoJSON topology into GeoJSON features for rendering.

United States Of America Map

This example displays a green choropleth map of the United States rendered as an SVG. It loads world country boundaries from the world-atlas TopoJSON dataset and isolates the U.S. geometry using `topojson.feature` and a name-based lookup. The map is projected with `d3.geoMercator` and drawn using `d3.geoPath` inside a D3 v5 script, with all paths styled via CSS.

USA Map By Sushil

This example displays a choropleth-style map of the United States using SVG. It shows state boundaries rendered as red strokes on a blank canvas, with states that change to blue on hover. The visualization loads TopoJSON data from `https://d3js.org/us-10m.v1.json` and converts it to GeoJSON features using `topojson.feature`. It draws the map with `d3.geoPath` and applies a mesh via `topojson.mesh` to outline borders. The styling uses CSS for hover effects and stroke widths.
