Forked from Cheap Tricks for Interaction

This interactive globe displays world countries colored red, with a zoom and pan interface that transforms the map projection. The visualization merges country boundaries from the world-atlas TopoJSON dataset with demographic attributes joined from tabular TSV data, matching records by ISO country codes. Using d3.geoPath with the Natural Earth projection, the code renders SVG paths and enables hover tooltips showing country names via SVG `<title>` elements. The zoom interaction relies on d3.zoom's event system, updating the group's transform attribute. The globe's sphere is filled blue, while countries use a red fill with a distinct hover state.

Cheap Tricks for Interaction

This interactive map shows world countries colored in light green on a blue sphere, with countries highlighted in red on hover. It uses d3.geoPath and d3.geoNaturalEarth1 for geographic projections and d3.zoom for pan/zoom interaction, rendering in SVG. Country names appear as tooltips via appended title elements, with data sourced from the world-atlas 50m TSV and TopoJSON files. The code imports from the d3 and topojson libraries.

Cheap Tricks for Interaction

This interactive map displays world countries as colored SVG paths on a globe, with country names shown as tooltips on hover. Built with D3 v5 and topojson, it uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` for generating vector outlines. A `d3.zoom` interaction enables pan and zoom transformations on the map group. Country names are joined from a TSV file (world-atlas 50m) using ISO numeric codes, and hover effects change fill to red via CSS.

This interactive map shows world countries on a globe, with each country filled with a distinct color from a rotating palette. Hovering over a country highlights it in black and displays its name via a tooltip, while the entire scene supports zoom and pan interactions. Built with D3 v5, the visualization uses `d3.geoPath` with a Mercator projection to render country outlines from the World Atlas TopoJSON dataset. Zooming is implemented through the `d3.zoom` API, which applies SVG transforms to the group element containing all paths.

This interactive map displays world countries and uses an equal-earth projection to render the globe. Hovering over a country changes its fill color to red, providing immediate visual feedback. The visualization is built with d3.geoPath and d3.geoNaturalEarth1 for map projection, while d3.zoom enables pan and zoom interactions. Country names come from a TSV file matching ISO codes, and geographic boundaries use TopoJSON data transformed via the `feature` function. The SVG output includes a styled sphere background and nation paths.

Cheap Tricks for Interaction

This interactive world map visualizes all countries on a natural Earth projection, initially rendered as uniformly red shapes against a dark blue sphere. Hovering over a country reveals its name via a tooltip, while a zoom interaction adjusts the map’s transformation. Built with d3.geoPath, d3.geoNaturalEarth1, and d3.zoom, it loads geographic data from the world-atlas package using topojson.feature. A CSS hover rule changes fill to red, though the static fill is already red, so the hover effect is subtle.

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 interactive map displays world countries on a natural Earth projection using SVG paths, with hover highlighting that changes country fill colors and zoom-and-pan capabilities via d3.zoom. The visualization loads geographic data from world-atlas TopoJSON and TSV files, using d3.geoPath and geoNaturalEarth1 to generate the map geometry. Country names are provided as tooltips through SVG title elements, with the sphere background filled blue and countries rendered in light green. The code demonstrates simple user interaction tricks like CSS hover effects and zoom transforms to enhance map exploration.

Cheap Tricks for Interaction

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.
