This example shows a world map with colored countries and two curved lines connecting points between South America and the Atlantic Ocean, drawn from a CSV file containing latitude and longitude pairs. The visualization uses d3.geoMercator for projection, d3.geoPath to render geographic features, and d3.zoom for panning and scaling the entire scene. Country data comes from a TopoJSON file loaded via topojson.feature, while a d3.json request fetches a GeoJSON world shape. Countries are assigned colors from a rotating palette, with hover effects turning them black.

Fork of Cheap Tricks for Interaction

This example shows an interactive world map that highlights countries in red on hover and displays country names as tooltips, with zoom and pan capabilities through the d3.zoom behavior. The visualization uses d3.geoNaturalEarth1 projection with d3.geoPath to render geographic features, sourcing country boundaries from the world-atlas TopoJSON dataset and matching names via TSV data. The SVG rendering includes a styled sphere background and country paths, with zoom transforms applied to a group element. Country names appear through SVG title elements appended to each path.

This visualization displays a world map using a natural Earth projection, with countries colored in light green that turn red on hover. It supports zooming and panning through the d3.zoom behavior, which applies transformations to an SVG group element containing all geographic paths. The map is rendered with d3.geoPath and d3.geoNaturalEarth1, using TopoJSON and TSV data from the world-atlas package to associate country names with their shapes via tooltips. The code imports specific D3 modules and the topojson feature function to generate the geographic features.

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 rendered with SVG paths. It presents countries in light green against a blue spherical background, and hovering over a country turns it red. The visualization uses a D3 geoNaturalEarth1 projection with a geoPath generator to draw continents from a world-atlas TopoJSON dataset. The code imports from d3.js v5 and TopoJSON, and it handles zooming and panning through D3’s zoom interaction, which applies a transform to the map group on zoom events.

Fork of Cheap Tricks for Interaction

This example shows an interactive world map built with D3.js, where hovering over any country turns it red and displays its name as a tooltip. The visualization renders a geo-projection sphere and country boundaries as SVG paths, using the `d3.geoNaturalEarth1` projection and `d3.geoPath` to generate the map geometry. The globe can be zoomed and panned via the `d3.zoom` API, which applies a transform to the grouped map elements. Country names come from a TSV data file joined with GeoJSON topology from the world-atlas package, processed with the topojson `feature` function.

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 shows an interactive world map with selectable countries, where hovering over a country reveals its name as a tooltip and highlights it in red. The map uses a natural Earth projection rendered as SVG paths, with a blue sphere background. It loads geographic data from the World Atlas TopoJSON and TSV files, joining country names by ID. The implementation relies on D3 v5 APIs including d3.geoPath, d3.geoNaturalEarth1, d3.zoom, and d3.json, along with a zoom transform applied to the map group for panning and scaling.

This interactive map displays world countries as SVG paths, with hover highlighting in red and a blue sphere background. Users can pan and zoom using d3.zoom, which applies transforms to the map group. The visualization loads world topology data from the World Atlas TopoJSON and country names from a TSV file, rendering with d3.geoNaturalEarth1 and d3.geoPath. The code uses d3.json and d3.tsv for data loading, and topojson.feature to extract country geometries.
