A world map renders each country as an SVG path using `d3.geoPath` and a Natural Earth projection, with data from the world-atlas TopoJSON source. A `d3.zoom` behavior on the SVG element applies pan and zoom transforms to a grouped layer, letting users scale and move the entire map. Hovering over a country triggers a CSS `:hover` rule that changes its fill to red, while a `<title>` element inside each path provides a native tooltip with the country name.

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 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.

A world map rendered with SVG paths uses d3.geoNaturalEarth1 and d3.geoPath to project country boundaries from TopoJSON data. A zoom behavior enables pan and zoom interactions that transform the map group. Country names from a TSV file are joined to features via an ID lookup, displayed as native SVG title tooltips on hover, while a CSS rule changes hovered countries to red.

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.

Cheap Tricks for Interaction

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.

Cheap Tricks for Interaction

This example demonstrates a world map with zoom and hover interactions, rendering countries as SVG paths using a Natural Earth projection. It relies on d3.zoom for pan and zoom transformations, d3.geoPath for projecting geographic data, and TopoJSON for country boundaries sourced from the world-atlas dataset. Country names are loaded from a TSV file, while hover effects change fill colors via CSS. The map also includes a spherical background and uses d3.select to manage the SVG container.

Cheap Tricks for Interaction

A world map rendered with D3 v5 uses a Natural Earth projection to display countries as filled paths with hover highlighting. The visualization demonstrates simple interaction techniques, including zooming via `d3.zoom` that applies a transform to the map group, and tooltip-like country names using SVG `<title>` elements. Country boundaries come from TopoJSON world-atlas data, while names are matched from a TSV file, with D3’s `geoPath` handling geometry projection.
