This example displays a choropleth map of the UK's European Electoral Regions, rendered as shaded polygons with gray fills and teal borders on a blank canvas. It loads GeoJSON boundary data from a GitHub repository using `d3.json`, then projects the coordinates with `d3.geoMercator`. The map is drawn through `d3.geoPath` directly onto a Canvas context, with React managing the page structure but not the map’s state. The visualization demonstrates combining D3’s geographic utilities with a canvas-based rendering pipeline.

AI-generated description

A program that loads in some data about CSS named colors using D3 utilities, and uses React state to keep track of the data.

Fork of Europe Map ICE8

This example renders a static map of Europe using D3.js and React, displaying geographic boundaries as SVG paths. The visualization employs a Mercator projection centered on latitude 13 and longitude 52, with paths generated via `d3.geoPath`. GeoJSON features are fetched from a remote URL and styled with grey strokes and white fills. The code references React 16.9.0, D3 v5, and TopoJSON, though it appears incomplete, as it mistakenly defines a `LondonProjection` and loads data from a CSV URL that may not provide valid GeoJSON.

Fork of Europe Map ICE8

This example renders a static map of Europe using React and D3 v5, drawing SVG paths from GeoJSON data fetched via `d3.json`. It applies a Mercator projection with `d3.geoMercator`, centered on coordinates [13, 52] and scaled to fit a 600×500 viewport. The `d3.geoPath` generator converts the geographic features into SVG path data, with each feature stroked in grey and filled white. The code explicitly requests state boundaries from a remote GeoJSON URL, indicating a straightforward choropleth-less basemap visualization.

Fork of England Regional Map

This example displays a choropleth-style map of England, highlighting the country’s geographical regions with a pink fill and purple interior borders. It uses the D3.js library’s `geoNaturalEarth1` projection and `geoPath` to render the geographic features, while TopoJSON’s `feature` and `mesh` functions convert the remote GeoJSON data. The React framework manages the rendering of the SVG elements, with the map’s states and boundaries clearly defined.

Fork of GeoVisualization - Choropleth map of the world

This example displays a choropleth map of the world, rendering country boundaries as gray paths on an SVG. When the user hovers over a country, its fill changes to red, and it reverts to gray on mouseout. The code loads GeoJSON data from a GitHub repository using `d3.json` and applies the `d3.geoEqualEarth` projection with `projection.fitExtent` to fit the map to the viewport. It uses `d3.geoPath` to generate the path data for each feature, with the SVG sized dynamically based on the window dimensions.

Fork of England Regional Map

A Choropleth-style map of England displays its administrative regions as solid teal polygons with thin gray borders separating neighboring areas. The visualization loads GeoJSON data from a remote URL and uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to render shapes as SVG paths within a React component. Region boundaries are derived via `topojson.mesh` to highlight only interior borders, while `d3.json` fetches the dataset in the `useData` hook.

Fork of React Starter

A choropleth map of world countries colors each nation by continent using a D3 geo path generator and a color scale. The visualization renders as an SVG globe inside a React component built with React hooks, fetching geographic data from the World Atlas TopoJSON and TSV files. Hovering reveals country names and indices appended as SVG title elements, while a transparent sphere outline frames the map. The code leverages d3.json, d3.tsv, and d3.geoPath to construct the projection and interactivity.

Fork of Working with

This example displays a world map visualization of the Data Canvas Sense Your City dataset, rendered as SVG paths. Using React hooks for state management, the code fetches TopoJSON country boundaries and converts them to GeoJSON with `topojson.feature`. The `d3.geoEqualEarth` projection and `d3.geoPath` generate the map shapes, which are styled with cyan fill and gray strokes. The visualization loads geographic data from the unpkg-hosted world-atlas package.

Fork of map with points

This example displays a choropleth-style map of the United States rendered as SVG paths, using React to manage component state and the d3.geoAlbersUsa projection with d3.geoPath to draw state boundaries from TopoJSON data loaded via the us-atlas package. The map is populated with geospatial features fetched from a remote URL, while a loading fallback appears until the data arrives. The visualization emphasizes the geographic outlines rather than quantitative values, with a single teal fill applied to all marks.
