This example shows a world map rendered with D3 v5, displaying countries as light green shapes on a blue sphere. Users can pan and zoom the map with mouse or touch input. The map loads geographic data from a TopoJSON world-atlas file, then draws it using an SVG path generator with a natural Earth projection. Country names are matched from TSV metadata and shown as tooltips. The implementation uses `d3.zoom`, `d3.geoPath`, and `d3.geoNaturalEarth1`, with hover effects changing country fill color via CSS.

Fork of Cheap Tricks for Interaction

This example shows an interactive world map with natural-earth projection, where countries appear as light green regions on a blue sphere and turn red on hover. Users can pan and zoom the map using mouse or touch gestures. Built with D3 v5 and TopoJSON, the visualization loads geographic data from the world-atlas repository, uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering, and implements zoom via `d3.zoom`. Country names are matched from a TSV file using ISO numeric codes.

Fork of Cheap Tricks for Interaction

This example presents an interactive world map using a natural Earth projection, with countries colored light green and the sphere filled blue. Hovering over a country turns it red and reveals its name via a tooltip, while users can zoom and pan by dragging. The visualization is built with D3 v5, using `d3.geoPath` and `d3.geoNaturalEarth1` for rendering the map, and `d3.zoom` for interaction. It loads geographic data from the world-atlas package (JSON and TSV files) and leverages the TopoJSON library to convert topology into features.

This example shows a world map rendered in SVG using D3.js v5. Countries are drawn with `d3.geoPath` and a `geoNaturalEarth1` projection, using TopoJSON data from the world-atlas package. The map supports pan and zoom via `d3.zoom`. Hovering over a country changes its fill color and displays the country name in a tooltip, which is generated from a TSV file using `d3.tsv`. The visualization demonstrates simple, lightweight interactions built entirely with D3's declarative SVG and data-binding APIs.

Fork of Cheap Tricks for Interaction

This example shows a world map with countries rendered in light green, where clicking a country turns it red, and users can zoom and pan the view. It uses an equirectangular-like natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to draw SVG paths from TopoJSON data loaded from the world-atlas package. Country names come from a TSV file, and a `d3.zoom` handler applies transforms to the map group. A spherical background and active-state styling complete the interactive visualization.

Fork of Cheap Tricks for Interaction

This example displays a world map rendered with SVG paths generated by `d3.geoPath` and the `geoNaturalEarth1` projection, using TopoJSON data from the world-atlas package. Country names are loaded via TSV and added as `<title>` tooltips. The visualization supports pan and zoom through `d3.zoom`, with a `g` element’s transform updated on zoom events. Countries are styled with white fills that turn gold on hover, while the background sphere uses a dark teal fill.

This example shows a world map with interactive pan and zoom capabilities, using a natural Earth projection rendered as SVG paths. The map displays country boundaries with light green fill, which turns red on hover, and includes tooltips showing country names from the world-atlas TSV data. The code uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom to handle the projection and view transforms, while d3.json and d3.tsv load the TopoJSON geometry and name mappings. The sphere background is styled blue, and the map supports fluid zooming through the d3.zoom event handler.

Fork of Cheap tricks for interaction D3 version 5

This interactive map displays world countries using a Natural Earth projection, with hover highlighting and zoom-and-pan capabilities. The visualization renders SVG paths generated by `d3.geoPath` and `geoNaturalEarth1`, while `d3.zoom` applies transform updates to the map group. Country names come from a TSV file joined to TopoJSON geometry via `d3.json` and `topojson.feature`. Hover states change country fill colors, and the sphere background uses a distinct blue fill.
