This interactive world map displays country boundaries on a natural Earth projection, with hover highlighting and zoom/pan functionality. The visualization loads geospatial data from the world-atlas TopoJSON and TSV files, rendering countries as SVG paths using d3.geoPath and d3.geoNaturalEarth1. The d3.zoom behavior enables interactive transformations, while country names are mapped from the TSV data and displayed as SVG title tooltips. The map uses d3 v5 and the topojson client library for feature extraction.

Make an Interative World Map w/ D3.js

This interactive world map displays country boundaries projected with a natural Earth projection, rendered as SVG paths that change color on hover and support zooming and panning. The visualization uses d3.geoPath and d3.geoNaturalEarth1 for geographic rendering, d3.zoom for interaction, and TopoJSON to convert world-atlas data. Country names come from a TSV file matched by ISO numeric codes, with tooltips showing each nation’s name via SVG title elements.

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.

Let's make an interactive map with D3.js!

This interactive map visualizes world countries with hover highlighting, displaying country names as tooltips. It uses the D3.js v5 library with the `geoNaturalEarth1` projection and `geoPath` for rendering map features. The visualization loads geographic data from the world-atlas package, combining TSV metadata and TopoJSON geometry, while `topojson.feature` processes the country boundaries. The map supports zooming through D3’s `zoom` event, and renders as an SVG with styling for the ocean sphere and landmasses.

Let's Make a Map With D3.js !

This example displays an interactive world map rendered with SVG paths, using D3.js v5 and TopoJSON data from the world-atlas package. It shows country boundaries with hover effects, built using `geoNaturalEarth1` projection and `geoPath` for geometry generation. The map supports pan and zoom through D3’s `zoom` behavior, transforming a group element. Country names are loaded from a TSV file and appended as SVG `<title>` tooltips, while the styling is defined in an external CSS file.

Let's make a map with D3.js!

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.

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.

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

This interactive world map displays country boundaries using a natural Earth projection, with hover tooltips showing country names and zoom/pan controls for exploration. It loads geographic data from the world-atlas TopoJSON and TSV files, then renders countries with D3’s `geoPath` and `geoNaturalEarth1`. The visualization uses `d3.zoom` for interaction and `topojson.feature` to convert TopoJSON geometry, with hover effects styled via CSS.
