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.

A world map rendered with SVG paths displays countries in light green against a blue sphere, with red highlighting on hover. The visualization uses D3 v5’s geoNaturalEarth1 projection and geoPath to draw geographic features from TopoJSON world-atlas data, while country names come from a TSV file. Pan and zoom interaction is implemented via d3.zoom, applying transforms to a group element. Tooltips are provided by SVG `<title>` elements showing each country’s name.

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.

A world map rendered with D3 v5 displays countries as light green SVG paths with hover highlighting in red. Using the Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, the map loads country boundaries from TopoJSON data through `d3.json`. Pan and zoom interactions are implemented with `d3.zoom` applied to an SVG group, transforming the entire map on input. Hover effects rely purely on CSS `.country:hover`, while country names appear through appended SVG `<title>` elements.

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 a world map highlighting countries in light green on a blue sphere, with a red hover effect on individual countries and zoom-and-pan interaction. It uses D3 v5 with d3.geoNaturalEarth1 projection, d3.geoPath, and d3.zoom to enable the viewport transformations. Country boundaries come from the World Atlas TopoJSON dataset, while country names are matched via the accompanying TSV file. The map renders as SVG, with hover tooltips provided by native `<title>` elements.

Cheap Tricks for Interaction

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.

This example shows a world map with countries rendered in light green against a dark blue sphere, drawn using D3’s `geoPath` and `geoNaturalEarth1` projection. Hovering a country turns it red, while a zoom interaction (via `zoom`) allows mouse-driven pan and scale. The map data comes from a TopoJSON file and a TSV file paired through `Promise.all`; the SVG output is generated by projecting geographic features, with tooltips provided by `title` elements.
