This example shows a natural Earth projection of the world map, with countries filled in yellow and a green sphere background. Hovering a country turns it blue and reveals its name via a tooltip. It loads GeoJSON country boundaries from the world-atlas dataset and country names from a TSV file, then renders them as SVG paths using d3.geoPath and d3.geoNaturalEarth1. The code uses d3.json, d3.tsv, and topojson.feature for data processing, with React managing the component structure.

lets make a map

This example displays a natural Earth projection map of the world, rendered as an SVG with countries filled in light green and a blue sphere background. It loads GeoJSON country boundaries from the World Atlas TopoJSON dataset, converts them using topojson.feature, and draws them with d3.geoPath and d3.geoNaturalEarth1. The code appends a sphere outline and country paths to a 960x500 SVG container.

Map of the World

This example visualizes the world using a Natural Earth projection, displaying landmasses, country borders, a graticule, and the spherical outline of the globe. The map renders as SVG, with land filled in yellow and interiors drawn as gray mesh lines. It loads geographic data from the World Atlas TopoJSON via `d3.json` and converts it into GeoJSON features using `topojson.feature` and `topojson.mesh`. The visual marks are generated with `d3.geoNaturalEarth1` and `d3.geoPath`, while React manages the component structure.

World Map

This example renders a world map using the Natural Earth projection, displaying country boundaries and graticule lines. The visualization shows landmasses filled with a teal color, country interiors outlined, and the sphere background in light gray. The code uses React for component structure and d3-geo functions like `geoNaturalEarth1` and `geoPath` to project and draw geographic features. TopoJSON data from the world-atlas package is loaded and converted to GeoJSON using `feature` and `mesh`.

World Map

This example renders a world map using a natural Earth projection, displaying countries as filled polygons, along with graticules, interior borders, and a sphere outline. It loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON using the `feature` and `mesh` functions from topojson. The map is drawn with `d3.geoPath` and `d3.geoNaturalEarth1`, while React manages the component structure and SVG rendering. Styling is applied through CSS classes, including a teal fill for landmasses and gray graticules.

Map

This example displays a world map using a natural Earth projection, with countries shown as light green shapes against a dark blue sphere background. The visualization is rendered as SVG paths derived from TopoJSON data loaded from the world-atlas package, with each country’s boundaries drawn using D3’s geoPath and geoNaturalEarth1 projection. The code utilizes D3 v6 for data binding and selection, while TopoJSON’s feature function converts the encoded topology into GeoJSON features for rendering.

World map

This example displays a world map using the Natural Earth projection, with landmasses filled in blue and country borders drawn as interior lines. A gray graticule grid overlays the sphere, and the entire map is rendered as SVG. The visualization uses React to manage the component structure, D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to compute projections and paths, and TopoJSON to convert country and land topology from the world-atlas dataset into GeoJSON features.

test

This example displays a world map using a natural Earth projection, with countries rendered as white shapes bordered by green strokes against a yellow sphere background. The visualization loads geographic data from the world-atlas TopoJSON dataset, converting it to GeoJSON features with the topojson feature method. D3’s geoPath and geoNaturalEarth1 are used to generate the projection and path data, while selections append each country path to the SVG canvas.

Lets make a Map

This example shows a world map rendered as an SVG, with countries filled in light green and oceans depicted as a blue sphere. It uses D3’s `geoNaturalEarth1` projection and `geoPath` to generate the map geometry. Geographic data comes from the World Atlas TopoJSON file, loaded via `d3.json` and converted to GeoJSON with `topojson.feature`. The complete React-based visualization is built with D3 v5 and TopoJSON v3, with styling applied through CSS classes.
