This example shows a world map colored by fertility rate per country, using a blue-to-white linear scale to indicate values. The map is built with D3 v4, loading GeoJSON topology from a GitHub repository and CSV data from another source, then joining them by country name. It uses `d3.geoMercator` for projection and `d3.geoPath` to draw country boundaries as SVG paths. The color scale is created with `d3.scaleLinear` and applied to each country’s fill, rendering a choropleth visualization in a static SVG canvas.

Fork of Fork of Fork of D3 world map example with TopoJSON to GeoJSON and circular indicators

This example visualizes a choropleth world map where each country’s fill color reflects its birth rate, using a linear blue scale. It also plots four city locations (Fairbanks, Boston, Philly, COS) as small circles, positioned via a Mercator projection with `d3.geoPath`. The map is built with D3 v4, loading GeoJSON country boundaries and CSV data via `d3.json` and `d3.csv`. The code uses `d3.geoMercator`, `d3.scaleLinear`, and `d3.extent` to drive the color mapping and projection.

Fork of Fork of Chloropleth

This example displays a choropleth map of the world, coloring countries based on their "Birth Rate" from a 2023 world-data CSV. A blue-to-red linear color scale encodes the data range, with grey indicating missing countries. The visualization renders two separate SVG canvases side-by-side, each showing the same map. The code loads GeoJSON map data, country statistics, and continent data using `Promise.all` and `d3.json`, `d3.csv`, then draws the map with `d3.geoEqualEarth` and `d3.geoPath`.

Fork of Fork of D3 world map example with TopoJSON to GeoJSON and circular indicators

This D3.js v4 world map visualizes birth rates per country using a Mercator projection, coloring each nation on a white-to-blue linear scale. The map draws country boundaries as SVG paths from a TopoJSON-to-GeoJSON dataset, with the `d3.geoMercator` and `d3.geoPath` APIs converting geographic coordinates into planar shapes. Circular indicators mark four specific cities—Fairbanks, Boston, Philly, and COS—positioned via the same projection. The choropleth colors are derived from a CSV file loaded through `d3.json` and `d3.csv` deferred queues.

World Map Visualization

A world map visualization colors each country according to a numeric value from an external CSV dataset. The example uses D3 v6 with a Mercator projection via `d3.geoMercator` and `d3.geoPath` to render GeoJSON country boundaries as SVG paths. Country fill colors are determined by a sequential blue color scale, while missing data appears gray. The code demonstrates loading remote TopoJSON and CSV files with `d3.json` and `d3.csv`, and includes an ES6 module import for a simple message.

Fork of Map

This example displays a world map colored according to a small set of country population figures, using lighter blue shades to represent higher values. It renders countries as SVG paths through `d3.geoPath` and the `geoEqualEarth` projection, with a Title and Labels for each of the eleven populated countries. The map loads TopoJSON from the `world-atlas` dataset via `d3.json`, and uses a `d3.scaleSequential` with `d3.interpolateBlues` to map populations. A legend in the top-left corner communicates the color scale range.

Map Example

This example visualizes global life expectancy by coloring countries on a Mercator-projected world map, with a white-to-blue linear color scale mapping values. Hovering a country fades others to 50% opacity, highlights the selected one, and outlines it with a black stroke. Built with React and SVG, it uses d3.geoPath with a geoMercator projection to draw GeoJSON features, d3.queue to load data, and d3.csv to parse the 2023 world dataset. Data includes a d3.map storing life expectancy per country, with colors applied via a scaleLinear domain from the data’s extent.

Making Maps

This example shows a choropleth world map where a small set of countries are shaded from light blue to dark blue according to their population in millions, taken from an inline data array. It uses D3 v7, TopoJSON’s `feature` function, a `d3.scaleLinear` color scale, and `d3.geoNaturalEarth1` projection with `d3.geoPath` to render countries from the world-atlas dataset as SVG paths. The map displays tooltips with each country’s name and population or “n/a” for unlisted countries.

Untitled

This example shows a world map colored by population data, though the color encoding is incomplete as the code only logs country IDs to the console instead of applying the fill. It uses D3 v4 with `d3.geoMercator` projection, `d3.geoPath` for rendering countries as SVG paths, and a `d3.scaleThreshold` with `d3.schemeBlues` for potential color mapping. The external data includes a GeoJSON world topology and a CSV of country population values, loaded asynchronously via `d3.queue`. The map is rendered as an SVG element with a fixed width and height.
