Cheap Tricks for Interaction

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.

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 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 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 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.

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.

Cheap Tricks for Interaction

This example shows a world map that users can pan and zoom, with countries displayed as light green regions that turn red on hover. The visualization loads geographic data as TopoJSON from the world-atlas package and renders it as SVG paths using d3.geoPath with a d3.geoNaturalEarth1 projection. Interaction is implemented through d3.zoom, while country names are joined from a TSV file and displayed via SVG title tooltips.

This example shows an interactive world map with zooming and panning controlled by the mouse. Hovering a country turns it red, and a tooltip displays the country’s name. Built with D3 v5, it uses `d3.geoNaturalEarth1` for the projection, `d3.geoPath` to generate the country shapes, and the `zoom` behavior from the `d3` module to apply transforms on a zoom event. The map draws a blue sphere background and green countries, using TopoJSON shape data and TSV country names from the `world-atlas` package.
