This example demonstrates interactive pan and zoom on a natural Earth projection map of world countries. Users can drag to pan and scroll to zoom, with the map updating smoothly through D3’s zoom behavior. The visualization renders country boundaries from the world-atlas TopoJSON dataset, using d3.geoPath and d3.geoNaturalEarth1 to project the geometry into SVG paths. Hovering highlights a country in red, and the map includes a blue sphere background. The code relies on d3.json for data loading and topojson.feature for converting TopoJSON to GeoJSON.

Map with interaction

This example shows an interactive map of world countries rendered as SVG paths using the Natural Earth projection. Users can pan and zoom the map via d3.zoom, which applies a transform to the grouped map elements. The map loads GeoJSON data from the world-atlas TopoJSON file, converts it with topojson.feature, and draws each country using d3.geoPath. Countries fill light green and turn red on hover, with the surrounding sphere rendered in blue. The visualization demonstrates basic geographic mapping with interactive zooming and hover feedback.

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

This interactive map displays world countries using a natural Earth projection rendered as SVG paths. Users can pan and zoom the map via D3’s `zoom` behavior, which applies transforms to a group element. Country boundaries come from TopoJSON data, with names joined from a TSV table using `reduce`. Hovering highlights a country in red, while the background sphere is colored blue. The code leverages `d3.geoPath`, `d3.geoNaturalEarth1`, and topojson’s `feature` method to generate the geographic shapes.

Map Interaction Assignment

This interactive map visualizes global country boundaries using a natural Earth projection, rendered as SVG paths within a zoomable viewport. The map shows the sphere as a blue background and individual countries in green, which turn red on hover, with country names displayed as tooltips. Built with D3 v5, the example uses `d3.geoNaturalEarth1`, `d3.geoPath`, and the `topojson` library’s `feature` function to process world atlas data loaded from TSV and JSON files. A zoom interaction, implemented via D3’s `zoom` event, transforms the map group, allowing users to explore the geographic data.

Map Interaction Assignment

This example shows an interactive world map where each country is rendered as a filled path, and hovering over a country turns it red. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with country boundaries loaded from TopoJSON data in the world-atlas package. Zoom and pan interactions are implemented using `d3.zoom`, which applies a transform to the map group. Country names are matched from ISO codes in a TSV file and displayed as tooltips using SVG `<title>` elements.

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!

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.

Tricks for Interaction

This example shows an interactive world map that supports pan and zoom navigation. The visualization renders a natural Earth projection using SVG paths, with each country drawn in light green and outlined in black. Hovering over a country changes its fill color to red, while a tooltip displaying the country name appears. The implementation uses D3 v5 APIs including `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.zoom`. Country boundaries come from the world-atlas TopoJSON dataset, joined with names from a TSV file. User interactions are handled by the zoom behavior, which applies SVG transform attributes to the map group.

Map Interaction with D3.js

This example shows an interactive map of world countries that users can pan and zoom, with countries highlighted in red when hovered over. It renders a Natural Earth projection using D3’s `geoNaturalEarth1` and `geoPath` within an SVG. The map loads world geometry from TopoJSON via `world-atlas` and country names from a TSV file, merging them by ISO code. Zooming is handled with `d3.zoom` and `event.transform` on the entire map group, while each country’s `title` tooltip displays its name.
