This example presents a world map with red circles marking a curated list of cities, including Tokyo, London, and Easter Island. The map is built using D3.js version 3 with a Mercator projection and TopoJSON data for country boundaries. Users can pan and zoom the map via the d3.behavior.zoom API, while a tooltip-like styled div is defined but not activated. City coordinates are projected onto the SVG canvas using d3.geo.path.

This example displays a world map rendered as SVG paths, colored grey with thin white stroke lines separating countries. The map uses the Mercator projection, centered on the prime meridian and rotated to show the eastern hemisphere. Users can pan and zoom interactively via a d3.zoom handler, which applies a transform to the grouped country paths during the zoom event. The geographic data comes from a TopoJSON file loaded with d3.json, and the features are extracted using topojson.feature before being drawn with d3.geoPath. The projection is configured with d3.geoMercator, and the zoom scale is restricted to a range of 1 to 8.

This example shows a world map rendered as gray countries with white borders, overlaid with white circles marking populated places from Natural Earth data. Hovering over a country or city highlights it in pink or blue, respectively. The visualization uses D3 v3's `d3.geoMercator` projection and `d3.geoPath` to draw GeoJSON features from two remote sources: world-110m.geojson for countries and ne_50m_populated_places_simple.geojson for places. Circles are positioned via the projection’s coordinates and respond to mouseover and mouseout events.

A world map displays cities with populations exceeding 50,000 as semi-transparent teal circles scaled by population size. The visualization uses d3.geoNaturalEarth1 for projection and d3.geoPath to render landmasses, country interiors, and graticules from World Atlas TopoJSON data. City coordinates and populations are loaded via d3.csv, with circles positioned using the projection and sized through a linear scale. The SVG is built in React, with static styling applying a light fill to land and subtle borders.

Adding names to places

This example shows a world map with red dots marking cities and their names placed just above each point. It uses D3.js version 3.5.17 with a Mercator projection and TopoJSON to render country outlines from a world-110m2.json file. City coordinates are loaded from a CSV file and plotted using `d3.geo.path`. The city labels are SVG text elements anchored above each circle, and each dot links to a Google search for that city. The map supports zoom and pan through `d3.behavior.zoom`.

Let's make a map with D3.js!

This interactive SVG map visualizes world countries, highlighting each one in red on hover and displaying its name via a tooltip. Built with D3.js v5, it uses `geoMercator` projection and `geoPath` to render geographic features from TopoJSON data, while country names are loaded from a TSV file. The map supports zooming through D3's `zoom` event, which transforms the map group.

Map Pan / Zoom with Cities and Text v5

This example displays an interactive map of the world centered on the Pacific, overlaid with red circular markers for eleven cities and their labels. Pan and zoom controls are implemented using the `d3.zoom` API, which applies SVG `transform` attributes to all map paths, circles, and text. The map geometry and city positions are projected using `d3.geoMercator` and `d3.geoPath`, with country outlines loaded from a TopoJSON file. City coordinates come from a CSV loaded via `d3.csv`, and text labels are placed above each marker, each linking to a web search.

World map with zoom / pan and cities

This example presents a world map rendered with SVG, featuring zoom and pan controls. It overlays red circular markers on select global cities, which are loaded from a CSV file and positioned using the Mercator projection via `d3.geo.mercator()`. Each city marker is hyperlinked to a Google search for its name. The map’s geography is drawn from a TopoJSON file, with paths generated through `d3.geo.path()`, while zooming and panning are handled by `d3.behavior.zoom()`.

This example shows an interactive world map that displays country borders and names, with a dark blue ocean sphere and light green landmasses. The map uses the Natural Earth projection via `d3.geoNaturalEarth1` and renders geographic features as SVG paths generated by `d3.geoPath`. Hovering over a country changes its fill to red, and a `zoom` behavior applies pan and zoom transforms to the map group. Country data comes from the world-atlas TopoJSON file, converted with `topojson.feature`.
