This example demonstrates an interactive world map using D3 v5 and TopoJSON data from the world-atlas package. It renders countries with the Natural Earth projection via d3.geoPath, applies an ocean sphere outline, and colors landmasses light green with black strokes. The map supports panning and zooming through d3.zoom, highlights countries in red on hover via CSS, and displays country names using tooltips sourced from a TSV lookup file.

Let's make a map with D3.js!

This example demonstrates how to create an interactive world map using D3.js v5 and TopoJSON. It renders a natural Earth projection with country boundaries, showing country names as hover tooltips and enabling zoom and pan through d3.zoom. The visualization loads geographic data from the world-atlas package, combining TopoJSON geometry with TSV metadata for country names. The map uses an SVG rendering approach, with countries styled as light green polygons that darken on hover, all implemented through d3.geoNaturalEarth1, d3.geoPath, and d3.json.

D3 course - World Map

This example displays a world map rendered as an SVG, using a natural Earth projection to show countries, graticules, and a stylized globe with colored landmasses and ocean. It loads GeoJSON data from the world-atlas TopoJSON file, converting it with `feature` and `mesh` from topojson. The visualization uses `d3.geoPath` and `d3.geoNaturalEarth1` for projections, React hooks for data fetching, and CSS to style the map elements.

d3 Visualization Map

This example displays a zoomable world map using a natural Earth projection, with countries colored light green and the ocean rendered as a blue sphere. Built with D3 v5 and TopoJSON, it loads country boundaries from the world-atlas dataset (50m.json) and names from 50m.tsv. The map supports interactive pan and zoom via d3.zoom, while d3.geoPath and geoNaturalEarth1 handle geographic rendering. Countries highlight red on hover, with tooltips showing country names. The visualization is rendered as SVG, with the sphere and country paths generated from the projected GeoJSON features.

Let's make a map with D3.js!

This example uses D3.js to render an interactive world map from TopoJSON and TSV data loaded from the world-atlas package. Countries are drawn as SVG paths using the d3.geoNaturalEarth1 projection and d3.geoPath, with hover effects changing their fill color. The visualization incorporates d3.zoom to enable pan and zoom transformations on the map group, while a sphere background is rendered from a GeoJSON Sphere object. Country names are joined to features via ISO numeric codes and displayed as SVG title tooltips.

world map interaction

This example presents an interactive world map built with D3.js v5, displaying country boundaries and names sourced from the world-atlas TopoJSON dataset. Users can zoom and pan the map using d3.zoom, with the transform applied to a group element. Countries are rendered as SVG paths via d3.geoPath and a natural Earth projection, with tooltips showing country names from the TSV file. Hovering highlights countries in red, while the ocean sphere uses a blue fill.

World Map

This example displays an interactive world map using a natural Earth projection, with countries rendered as filled paths that highlight red on hover. The visualization loads geographic data from the world-atlas TopoJSON and TSV files, joining country names via ISO codes. It uses d3.geoPath with geoNaturalEarth1 for projection, d3.zoom for pan and zoom interactions, and TopoJSON’s feature method to convert topology to GeoJSON. The SVG sphere appears blue, while countries are light green with black strokes.

D3.js map - interactive

This interactive map displays world countries shaded in light green against a light blue sphere, with hover highlighting in red. Built with D3.js v7 and TopoJSON, it projects geographic data from the world-atlas countries-50m dataset using a natural Earth projection via d3.geoPath and d3.geoNaturalEarth1. Zoom functionality is handled by d3.zoom, which applies interactive transforms to the SVG group.

This example shows an interactive world map built with D3.js v5, rendered as SVG. It displays country boundaries and names from the world-atlas TopoJSON dataset using a Natural Earth projection, with the ocean filled blue and countries in green. The map supports pan and zoom through d3.zoom, which applies transform updates to the entire map group. Hovering highlights individual countries in red via CSS. The code uses d3.geoPath and d3.geoNaturalEarth1 for geographic projections and feature conversion from TopoJSON.
