This example shows an interactive world map rendered in SVG using D3 v5, where countries appear in light green against a dark blue spherical background. Users can zoom and pan the map via a d3.zoom handler that applies SVG transforms to the map group. Natural Earth projection is applied through d3.geoNaturalEarth1, with country boundaries drawn via d3.geoPath. Country names come from a TSV file joined to TopoJSON geometry using topojson.feature, and hovering highlights a country in red via a CSS :hover rule.

Cheap Tricks for Interaction

This example shows an interactive world map rendered with SVG, where country boundaries appear in light green and turn red on hover, with a blue sphere background. It uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to draw geographic features from TopoJSON data loaded via `d3.json`. Country names come from a TSV file accessed with `d3.tsv`. The map supports pan and zoom through `d3.zoom`, applying the current transform to a group element containing all countries.

Cheap Tricks for Interaction

This example shows an interactive world map rendered with SVG, where each country is colored light green and the sphere background is dark blue. A D3 zoom behavior allows users to pan and scale the map by applying transform attributes to the map group. The code uses `d3.geoPath` with a natural Earth projection and TopoJSON data from the world-atlas package to draw country boundaries. A TSV file provides country names, which are displayed as tooltips via SVG `title` elements, and hovering changes the fill color to orange.

Cheap Tricks for Interaction

This example shows an interactive world map rendered in SVG, with country boundaries displayed in light green and a blue sphere backdrop. Users can zoom and pan the map using their mouse or touch gestures, while hovering over a country highlights it in red and reveals its name as a tooltip. The visualization uses D3 v5’s `geoNaturalEarth1` projection, `geoPath`, and `zoom` behavior, with TopoJSON data from the world-atlas package. Country names are joined from a TSV file using ISO numeric codes, and the map is drawn from TopoJSON features converted with `feature`.

Cheap Tricks for Interaction

This example shows an interactive world map rendered in SVG, where each country appears in light green with a black outline and displays its name via a tooltip on hover. Users can pan and zoom the map using mouse interactions, which transforms the entire map group. The visualization uses D3 v5 with `d3.geoNaturalEarth1` for projection, `d3.geoPath` for drawing country boundaries, and `d3.zoom` for interaction. Country geometries come from the world-atlas TopoJSON dataset, with country names loaded from a matching TSV file, while CSS hover effects turn countries red under the cursor.

Cheap Tricks for Interaction

This example shows an interactive world map where hovering highlights countries in red against a light green base, with zoom and pan enabled for exploration. The visualization uses D3 v5 with a Natural Earth projection (d3.geoNaturalEarth1) and d3.geoPath to render country boundaries from TopoJSON world atlas data, linked to country names via TSV metadata. Interactions rely on d3.zoom for panning and zooming, while CSS :hover rules change country fill colors. The SVG-based map includes a blue sphere background, and the code loads data using Promise.all with d3.json and d3.tsv.

The visualization uses D3 v5’s `d3.zoom` to apply a transform to a group element, while countries are drawn using `d3.geoPath` with a natural Earth projection. Geographic data comes from the world-atlas TopoJSON and TSV files, which supply country boundaries and names for tooltips.

Cheap Tricks for Interaction

A world map rendered in SVG with D3 v5 uses a natural Earth projection to display countries colored in light green. Hovering over a country turns it red, and scrolling or dragging applies zoom and pan interactions via the d3.zoom API. Country names come from a world-atlas TSV file and appear as tooltips through SVG title elements, while the map data loads from TopoJSON.
