A world map rendered with D3.js displays country boundaries filled in light green on a light blue sphere, using natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`. Hovering highlights a country in red with a tooltip showing its name from the World Atlas TSV data. The map supports zoom and pan through `d3.zoom`, applying transforms to the SVG group. TopoJSON from world-atlas provides geometry, processed with `topojson.feature`. The visualization demonstrates combining geographic data, interactive controls, and CSS styling in an SVG context.

Let's make a map with D3.js!

This example shows an interactive world map rendered with D3.js, displaying country boundaries colored light green that turn red on hover. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw geographic features, with zoom support through `d3.zoom`. It loads world-atlas TopoJSON data and a companion TSV file to map country names, appending tooltips with each country’s name. The map is drawn as SVG paths, including a dark blue sphere background.

Let's make a map with D3.js!

This example shows an interactive world map built with D3.js, displaying country boundaries as SVG paths colored light green, with a blue sphere background. The map supports zooming and panning through a d3.zoom behavior, and hovering over a country turns it red. It uses d3.geoNaturalEarth1 for projection and d3.geoPath for generating paths from TopoJSON data loaded from the world-atlas package, with country names joined from a TSV file and displayed as tooltips via SVG `<title>` elements.

Let's make a map with D3.js!

This example shows an interactive world map built with D3 v5, displaying country boundaries and names loaded from the World Atlas TopoJSON and TSV datasets. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and renders countries as SVG paths generated with `d3.geoPath`. Hovering highlights a country in red, and a zoom behavior implemented with `d3.zoom` allows pan and zoom. A light blue sphere background and green country fills demonstrate basic choropleth styling.

Let's make a map with D3.js!

A world map rendered in SVG shows country boundaries as light green paths against a dark blue sphere, using a Natural Earth projection. The code loads world-atlas TopoJSON data from unpkg, converts it to GeoJSON with `topojson.feature`, and draws each country with `d3.geoPath`. The sphere outline is generated from a projected GeoJSON sphere object. D3 v5 handles the asynchronous JSON loading and DOM selection.

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.

Let's make a map with D3.js!

This example displays an interactive world map using a natural Earth projection, with countries rendered as green SVG paths that turn red on hover. The map supports zooming and panning through a D3 zoom behavior applied to the SVG group. The visualization uses d3.geoNaturalEarth1, d3.geoPath, and topojson.feature to parse geographic data from the world-atlas dataset. A semi-transparent blue sphere outlines the globe, while country names appear as tooltips via appended title elements.

Let's make a map with D3.js!

A world map drawn with D3.js shows country boundaries as SVG paths projected with the Natural Earth projection, with a dark sphere as the background. The visualization loads geographic data from the world-atlas TopoJSON file and renders each country as a filled path. Interactive mouseover and mouseout events change the fill color and stroke width of individual countries, providing immediate visual feedback. The code uses D3 v5 functions such as `geoPath`, `geoNaturalEarth1`, and `select` alongside the TopoJSON `feature` API.

Let's make a map with D3.js!

This example shows an interactive world map rendered as SVG, where each country is colored light green and turns red on hover, with a dark blue sphere backdrop. Built with D3.js v5 and TopoJSON, it uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to draw country boundaries from the World Atlas 50m dataset. Zoom and pan are enabled via `d3.zoom`, while country names are loaded from a TSV file and attached as SVG title tooltips.
