This example shows a Mercator map of the world centered on the Pacific Ocean, with red circles marking eleven cities from a CSV file. Users can pan and zoom the entire map and city markers using the d3.zoom behavior, with a scale extent of 1 to 8. The map is rendered as SVG paths from a TopoJSON file via d3.geoPath, while city positions are projected using d3.geoMercator. Each city circle is wrapped in a link that opens a Google search for that city.

AI-generated description

This is a simple map example with pan and zoom centered on the Pacific.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 6 of d3.js.

Map Pan / Zoom with Cities and Text v6

This D3.js (version 6) example displays a world map centered on the Pacific Ocean using a Mercator projection, with red circles marking cities from a CSV data file and city names as text labels. Each city is hyperlinked to a Google search for its name. The visualization supports pan and zoom interactions through the `d3.zoom` API, applying the zoom transform to the map paths, city circles, and text elements. The map geometry comes from a TopoJSON file processed with the `topojson` library, and all rendering uses SVG.

Map Pan / Zoom with Cities v5

This map example displays world country boundaries and major global cities, with interactive pan and zoom functionality centered on the Pacific Ocean. The visualization uses d3.geoMercator for projection and d3.geoPath to render geographic features from a TopoJSON world file. City locations from a CSV dataset are plotted as red circles, each hyperlinked to a Google search. Users can apply d3.zoom with a scale extent of 1 to 8, transforming both paths and circles accordingly. The map is rendered as SVG elements within a d3 selection.

Map Pan / Zoom with Cities v7

This example shows a pan-and-zoomable Mercator map of the world, centered on the Pacific Ocean, with city locations marked by red dots. The map uses an SVG rendering with countries styled as grey paths, and city coordinates are loaded from a CSV file containing airport codes, city names, and latitude/longitude values. Pan and zoom interactions are enabled through d3.zoom, which applies a transform to all map elements. The map itself is drawn using d3.geoPath with a d3.geoMercator projection, and world topology data is fetched as a JSON file, then converted via topojson’s feature function before being rendered.

Map Pan / Zoom with Cities and Text v7

This example shows a world map centered on the Pacific with red city markers and text labels for each city, all of which can be panned and zoomed together. The map is rendered using D3 v7 with a Mercator projection and a topojson world dataset. City positions are projected from latitude and longitude coordinates loaded from a CSV file. D3’s zoom behavior applies a transform to the map paths, circles, and text, and each city label links to a Google search for its name.

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()`.

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.

Map Pan and Zoom v5

This map of the world centers on the Pacific Ocean and lets users pan and zoom. It uses a Mercator projection via `d3.geoMercator` and renders country boundaries as SVG paths from TopoJSON data. The `d3.zoom` behavior applies a transform to the path group, enabling interactive navigation with a scale extent of 1 to 8.
