This example displays a choropleth map of geographic regions rendered as SVG paths, with each region colored uniformly. The visualization uses D3’s `d3.geoMercator()` projection and `d3.geoPath()` generator to transform GeoJSON features from a local `country.json` file into scalable vector graphics. The code loads D3 v6 via a CDN and demonstrates both D3 API imports and local ES6 module integration, though the primary map drawing relies solely on the built-in path generator to convert coordinate data into visible shapes.

Country/States Map Example

This example displays a geographic map rendered as SVG paths from GeoJSON data, showing country or state boundaries. It uses D3 v6’s `d3.geoMercator` projection and `d3.geoPath` to translate geographic coordinates into screen positions. The map is drawn by appending a `path` element for each feature in the loaded `country.json` file. The visualization focuses on the raw geometry of regions without additional styling or interactivity.

country map

This example displays a choropleth map of India, rendering each state as a distinct colored path using geographic features loaded from a GitHub gist. The visualization employs a Mercator projection via `d3.geoMercator` and converts TopoJSON data to GeoJSON features with the `topojson.feature` function. Each state is drawn as an SVG path generated by `d3.geoPath`, with fill colors assigned from `d3.scaleOrdinal` and `schemeCategory10`. The map includes a title and uses hover styling, with all rendering handled through React and D3 v5.

Country Map

This example displays a choropleth map of India rendered as an SVG, with each state filled using a categorical color scale. The visualization uses D3’s `geoMercator` projection, `geoPath`, and `scaleOrdinal` to draw the country’s boundaries from a TopoJSON file hosted on GitHub. Title text appears above the map, and hovering over any state highlights it in red via CSS. The code relies on the D3 v5, TopoJSON, and d3-geo-projection libraries.

Country Map with d3.js

This example displays a world map using D3.js, coloring individual countries based on sample population data. It shows a Mercator projection of the globe, with the United States and China shaded according to the provided values. The visualization constructs the map by appending SVG paths from GeoJSON data to the chart. It relies on D3 APIs including `d3.geoMercator`, `d3.geoPath`, `d3.json`, `d3.scaleLinear`, and `d3.extent` to handle the projection, rendering, and color encoding, with a domain from data values mapped to a light-to-dark color range.

Country Map

This example shows a choropleth map of the United States, with each state rendered as a green SVG path on a light blue background. It loads US state boundaries from the us-atlas TopoJSON file and uses the `d3.geoPath` projection with `d3.geoAlbersUsa` to create the map. The code relies on `d3.json` to fetch the data and the `topojson-client` library to convert TopoJSON features into GeoJSON paths for rendering.

Country map using d3.js

This example displays a choropleth map of India, with each state rendered as a green SVG path against a black background. It uses D3’s `geoMercator` projection and `geoPath` generator to create the geographic outlines. State boundaries are drawn from a TopoJSON file fetched from a GitHub repository, processed with the `topojson.feature` function. The map is built entirely with SVG elements, and the overall shape is outlined using a sphere path, while state paths are appended dynamically after the data loads.

My map

This example presents a choropleth-style map of a single region, likely a state, rendered as a filled polygon in a light blue SVG container. The map uses the Mercator projection and d3.geoPath to draw geographic boundaries from a GeoJSON file, while d3.csv loads city data for potential point markers. The visualization is built with D3 v5 and styled as a responsive SVG using a viewBox, with a custom CSS class for layout. The code demonstrates loading external data files and projecting them onto a large canvas.

Country Map

This example displays a choropleth map of the 50 US states, rendered as SVG paths with a blue fill and black state borders. The visualization uses the `geoAlbersUsaTerritories()` projection and `d3.geoPath()` to draw geographic features, while `useData` fetches TopoJSON data from the `us-atlas` package. State boundaries are generated via the `feature()` and `mesh()` functions from TopoJSON, and hovering highlights a state blue.
