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.

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.

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`.

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.

This example presents an interactive world map using D3.js and TopoJSON. It displays country boundaries from the world-atlas 50m dataset, rendered as SVG paths using the `geoNaturalEarth1` projection and `geoPath`. The map supports zooming via the `zoom` function, which applies a transform to the grouped elements. Hovering over a country highlights it in red through CSS, and clicking the sphere logs an event to the console, while country names appear as tooltips from a TSV lookup file.

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 a zoomable world map rendered with D3 v5 and TopoJSON, where hovering over any country highlights it in red. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw country boundaries from the world-atlas 50m dataset, with country names added as tooltips using `<title>` elements. Interaction combines `d3.zoom` on the SVG for pan and zoom transformations, plus CSS `:hover` styling for the highlight effect. The base map and sphere are drawn as SVG paths, with data joined from TSV metadata and JSON topology.

Cheap Tricks for Interaction

This example shows an interactive world map using a natural Earth projection, where countries render as light green polygons with black outlines on a blue sphere. Users can pan and zoom through the map, and hovering over any country highlights it in red while displaying its name in a tooltip. The visualization uses d3.zoom for interaction, d3.geoPath with d3.geoNaturalEarth1 for map projection, and topojson to convert TopoJSON data from the world-atlas package. Country names come from a TSV file matched by ISO numeric codes.
