This example demonstrates interactive pan and zoom on a natural Earth projection map. The visualization renders country boundaries from TopoJSON world-atlas data using `d3.geoNaturalEarth1` and `d3.geoPath`, with hover highlighting via CSS. The code applies `d3.zoom` to the SVG container, updating a transform attribute on a group element during zoom events. Country names from the `world/50m.tsv` file appear as tooltips using SVG `<title>` elements, while the sphere background and country fills come from external styles.

Cheap Tricks for Interaction

This example demonstrates interactive pan and zoom on a natural Earth projection map of world countries. Built with D3 v5, it uses `d3.zoom` to apply SVG transforms and `d3.geoPath` with `geoNaturalEarth1` for rendering. Country boundaries come from TopoJSON world-atlas data, with names matched via a TSV file and displayed as `<title>` tooltips. Hovering highlights a country in red, while the sphere background is blue.

Cheap Tricks for Interaction

This example demonstrates interactive pan and zoom on a world map, with countries highlighted in red on hover and tooltips displaying country names via SVG `<title>` elements. It uses a natural Earth projection (`geoNaturalEarth1`) and renders geographic features with `d3.geoPath`. The map loads world-atlas TopoJSON data and merges it with TSV country names, while the zoom behavior is implemented through `d3.zoom` applied to an SVG group.

This example demonstrates interactive zooming and panning on a natural Earth projection map, with country boundaries colored green and highlighting red on hover. It uses a world-atlas TopoJSON dataset merged with a TSV file to map country IDs to names, which appear as tooltips via SVG `<title>` elements. The implementation relies on d3.geoNaturalEarth1, d3.geoPath, d3.zoom, and topojson.feature to render and manipulate the geographic shapes within an SVG canvas.

Cheap Tricks for Interaction

This example demonstrates a world map with interactive pan and zoom, using a natural Earth projection rendered as SVG. Country boundaries are drawn from TopoJSON data enriched with names from a TSV file, and hovering highlights individual nations in red. The implementation relies on D3 v5 features including `d3.zoom`, `d3.geoPath`, and `d3.geoNaturalEarth1`, with the map contained in an SVG group that responds to zoom transforms. Tooltips are provided through SVG `<title>` elements.

Cheap Tricks for Interaction

This example shows a zoomable world map rendered as an SVG, with country names displayed as hover tooltips. The visualization uses a Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with geographic data loaded from the World Atlas TopoJSON and country names from its accompanying TSV file. The map supports pan and zoom through `d3.zoom`, and the code includes a commented-out `d3.behavior.zoom` variant. Country boundaries are drawn as light green paths with black strokes, while the ocean sphere is filled blue.

Cheap Tricks for Interaction

This example demonstrates how to enhance a natural Earth projection map with basic interactive affordances. Users can pan and zoom the world map, and hovering over any country highlights it in red. The map renders geographic data from the World Atlas TopoJSON and TSV datasets using `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.zoom`. Country names are joined from the TSV file and displayed as SVG `<title>` tooltips. Styling relies on CSS hover effects while the zoom behavior applies SVG group transformations.

Cheap Tricks for Interaction

This example shows a world map with countries filled in light green, rendered using a natural Earth projection in SVG. It demonstrates simple pan-and-zoom interaction by attaching a `d3.zoom` handler to the SVG, which applies the current zoom transform to a group element containing all country paths. The map loads country boundaries from TopoJSON in the world-atlas package and joins them with names from a TSV file, adding a `<title>` tooltip per country. The code uses `d3.geoPath`, `d3.geoNaturalEarth1`, and `d3.zoom` from D3 v5.

Cheap Tricks for Interaction

This example demonstrates interactive zooming and panning on a natural Earth projection map of world countries, with hover highlighting that changes each country’s fill to red. The map is rendered as SVG paths using `d3.geoPath` and `geoNaturalEarth1`, with country boundaries loaded from TopoJSON world-atlas data and names joined from a TSV file. Interaction is handled through `d3.zoom`, which applies a transform to a group element, while CSS `:hover` rules trigger the color change on each country.
