This example shows an interactive world map rendered with SVG, where hovering over a country highlights it in red and zooming is enabled through mouse or touch gestures. 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

This example shows an interactive world map rendered with SVG, where hovering highlights countries in red and clicking logs the selected country's ID. The visualization uses D3 v5's `geoPath` and `geoNaturalEarth1` projections to draw geographic boundaries, and the `zoom` interaction module enables pan and zoom transformations. Country names come from a TSV file loaded from the world-atlas package, while geometric data is parsed from TopoJSON using the topojson library.

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 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 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 where hovering over a country highlights it and clicking selects it, turning it red. The visualization uses the D3.js library, specifically `d3.geoNaturalEarth1` for the map projection and `d3.geoPath` for rendering country boundaries. It loads geographic data from the `world-atlas` package via `d3.json` and `d3.tsv`, using `topojson` to convert the TopoJSON features. The map supports zooming through the `d3.zoom` API, which dynamically transforms the SVG group containing the paths.

Cheap Tricks for interaction!

This example shows an interactive world map where hovering over a country turns it red and zooming with the mouse repositions the map. It uses D3.js v5 with `d3.geoNaturalEarth1` for the projection, `d3.geoPath` for rendering, and `d3.zoom` to handle pan and zoom transforms on the SVG group. Country boundaries come from the `world-atlas` TopoJSON file, with names joined from a TSV file. The visualization demonstrates fundamental DOM selection and data binding, alongside simple CSS hover styling.

Cheap Tricks for Interaction

This example displays a world map rendered as an SVG using a natural Earth projection, with countries colored light green on a blue sphere. Hovering over any country turns it red, and the entire map can be panned and zoomed. The visualization loads TopoJSON world data and a TSV file of country names from the world-atlas package, then creates map paths with `d3.geoPath`. Zoom interaction is handled through `d3.zoom` and event transforms, while hover styling is applied via CSS on the `.country` class, with tooltips provided by SVG `<title>` elements.
