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.

This example shows a world map rendered with a natural Earth projection, where countries are drawn as light green paths with a dark blue ocean background. Users can pan and zoom the map using a D3 zoom behavior, which applies a transform to the entire country group. The map data comes from the world-atlas TopoJSON and TSV files, processed with d3.geoPath and topojson.feature. Hovering over a country turns it red via CSS. The code explicitly uses d3.select, d3.json, d3.tsv, and d3.zoom to implement these interactions.

This example shows a world map with hover and zoom interactions. It renders country boundaries and names using a Natural Earth projection, with each country highlighted in red on mouseover. The visualization loads geographic data from the world-atlas TopoJSON dataset and joins it with country names from a TSV file. It uses d3.geoPath with d3.geoNaturalEarth1 to draw the map, d3.zoom to enable pan and zoom, and SVG title elements for tooltips.

This example shows a world map with country boundaries rendered in light green on a dark blue sphere, using d3.geoNaturalEarth1 and d3.geoPath. Hovering over a country turns it red, revealing its name via SVG title elements from world-atlas TSV data. Pan and zoom interactions are implemented with d3.zoom, which applies a transform to the map’s parent group element. The visualization uses topojson to parse the countries-50m.json TopoJSON file.

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 a natural Earth projection of world countries that users can pan and zoom. The map renders country boundaries as SVG paths with hover states that highlight each nation in red. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to project TopoJSON data from the world-atlas package, while d3.zoom enables interactive transformations. Country names are loaded from a TSV file and attached as SVG title elements for tooltips.

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.

A world map rendered in SVG shows country borders in light green on a blue sphere, with hover highlighting in red and zoom-and-pan interaction via `d3.zoom`. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to project geographic data from TopoJSON, with country names from a TSV file. Hover tooltips appear through SVG `title` elements. The code loads data from the world-atlas dataset and applies a `g` transform on zoom events.
