This example shows a world map with interactive pan and zoom capabilities, using a natural Earth projection rendered as SVG paths. The map displays country boundaries with light green fill, which turns red on hover, and includes tooltips showing country names from the world-atlas TSV data. The code uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom to handle the projection and view transforms, while d3.json and d3.tsv load the TopoJSON geometry and name mappings. The sphere background is styled blue, and the map supports fluid zooming through the d3.zoom event handler.

This example shows a natural Earth projection world map rendered with SVG, where individual countries appear in light green and turn red on hover. A zoom interaction lets the viewer pan and scale the entire map using the mouse. The code uses d3.geoPath with d3.geoNaturalEarth1 for projections, d3.zoom for interactive transforms, and topojson.feature to convert TopoJSON country boundaries. Country names come from a TSV file joined by ISO numeric codes, and the map background sphere fills blue.

Fork of Cheap Tricks for Interaction

This example shows an interactive world map rendered with SVG paths. It presents countries in light green against a blue spherical background, and hovering over a country turns it red. The visualization uses a D3 geoNaturalEarth1 projection with a geoPath generator to draw continents from a world-atlas TopoJSON dataset. The code imports from d3.js v5 and TopoJSON, and it handles zooming and panning through D3’s zoom interaction, which applies a transform to the map group on zoom events.

Fork of Cheap Tricks for Interaction

This example shows an interactive world map rendered in SVG using the natural Earth projection. Users can pan and zoom by dragging or scrolling, with the viewport transform applied to a group element. Country boundaries and names come from world-atlas TopoJSON and TSV data. The visualization uses d3.geoPath for geographic paths, d3.zoom for interaction, and CSS hover states that turn countries red. A sphere outline and background fill complete the globe-like appearance.

Fork of Cheap Tricks for Interaction

This example shows an interactive world map with selectable countries, where hovering over a country reveals its name as a tooltip and highlights it in red. The map uses a natural Earth projection rendered as SVG paths, with a blue sphere background. It loads geographic data from the World Atlas TopoJSON and TSV files, joining country names by ID. The implementation relies on D3 v5 APIs including d3.geoPath, d3.geoNaturalEarth1, d3.zoom, and d3.json, along with a zoom transform applied to the map group for panning and scaling.

This example presents an interactive world map using a natural Earth projection, with countries colored light green and the sphere filled blue. Hovering over a country turns it red and reveals its name via a tooltip, while users can zoom and pan by dragging. The visualization is built with D3 v5, using `d3.geoPath` and `d3.geoNaturalEarth1` for rendering the map, and `d3.zoom` for interaction. It loads geographic data from the world-atlas package (JSON and TSV files) and leverages the TopoJSON library to convert topology into features.

Fork of Cheap Tricks for Interaction

This example shows an interactive world map with natural-earth projection, where countries appear as light green regions on a blue sphere and turn red on hover. Users can pan and zoom the map using mouse or touch gestures. Built with D3 v5 and TopoJSON, the visualization loads geographic data from the world-atlas repository, uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering, and implements zoom via `d3.zoom`. Country names are matched from a TSV file using ISO numeric codes.

This example shows a world map rendered with D3 v5, displaying countries as light green shapes on a blue sphere. Users can pan and zoom the map with mouse or touch input. The map loads geographic data from a TopoJSON world-atlas file, then draws it using an SVG path generator with a natural Earth projection. Country names are matched from TSV metadata and shown as tooltips. The implementation uses `d3.zoom`, `d3.geoPath`, and `d3.geoNaturalEarth1`, with hover effects changing country fill color via CSS.
