This example shows a world map rendered from a TopoJSON file using a Mercator projection, with pan and zoom enabled for interactive exploration. The map is drawn as SVG paths via `d3.geoPath` and a `d3.geoMercator` projection, centered and scaled to display global geography. A `d3.zoom` handler updates the map’s transform and re-projects paths on each interaction. The code includes commented-out attempts to plot city coordinates from a CSV, but the visible implementation focuses solely on the country boundaries from the `world-110m2.json` data source.

World Map with zoom and pan

This example displays a world map rendered as gray SVG paths with white borders, centered on a Mercator projection. Users can pan and zoom the map via mouse interactions, with the view transform updating dynamically. The map data comes from the `world-110m2.json` TopoJSON file, processed using `topojson.object`, while D3’s `d3.geo.path` and `d3.behavior.zoom` handle the projection and interactive behavior.

World Map using Mercator Projection

This example displays a world map using the Mercator projection, rendered as SVG paths with countries filled in white on a blue ocean background. It loads GeoJSON country boundaries from a gist and uses `d3.geoMercator` for projection, `d3.geoPath` to generate the paths, and `topojson.feature` to convert TopoJSON data. A sphere outline is drawn first, and country paths are appended dynamically from the fetched dataset.

Untitled

A world map rendered in the Mercator projection displays country boundaries as grey paths with thin white strokes. The example demonstrates loading GeoJSON-derived topology data from a local `world-110m2.json` file and converting it to SVG paths using `d3.geoPath`. The map is centered and rotated with `d3.geoMercator` and `projection.rotate`, and country features are extracted via `topojson.feature` from the TopoJSON library. The page uses D3 v7 to fetch the data asynchronously with `d3.json` and append the resulting paths to an SVG container.

making a map

This example renders a world map using the Mercator projection, displaying country boundaries as SVG paths. The code loads geographic data from the World Atlas TopoJSON file, converts it to GeoJSON using `topojson.feature`, and draws the countries with `d3.geoPath`. The map is created with d3.v7, using a static SVG canvas sized to 960 by 500 pixels. The visualization demonstrates a straightforward approach to converting TopoJSON into a projected map with minimal styling.

let's make a world map

This interactive map renders world countries as SVG paths using a Mercator projection. The visualization loads country boundaries from a world-atlas GeoJSON/TopoJSON dataset and draws them server-side with D3’s `geoPath` and `geoMercator`. The code employs `topojson.feature` to convert topological data into geometric features, then appends each path to the SVG canvas.

worldmap

This example displays an interactive world map with countries rendered as individual SVG paths, colored light green with black outlines, and highlighted in red on hover. It uses D3 v5's `geoNaturalEarth1` projection with `geoPath` to draw the map, and a light blue sphere for the oceans. Country boundaries come from the `world-atlas` package's countries-50m GeoJSON data, and the `topojson-client` library converts TopoJSON to GeoJSON for feature extraction. The chart supports zooming via D3's `zoom` event, which updates the SVG group transform in real-time.

Map Pan and Zoom v6

This example demonstrates an interactive world map that supports panning and zooming, centered on the Pacific Ocean. The map renders country boundaries as SVG paths filled with grey, using the `d3.geoMercator` projection and `d3.geoPath` to generate the geometry. A `topojson` data file supplies the world topology. The `d3.zoom` API applies a transform to the SVG group containing the paths, with a scale range between 1x and 8x, enabling the user to explore the map.

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()`.
