This example shows an interactive world map colored by economic classification, using a sequential spectral color scale. Users can pan and zoom the map via d3.zoom, which applies a transform to the geographic group. Hovering highlights individual countries with a red fill via CSS. The visualization loads country boundaries from TopoJSON and metadata from TSV, projecting them with d3.geoNaturalEarth1 and rendering paths with d3.geoPath. It uses d3.scaleOrdinal and d3.schemeSpectral to map economic data to colors, with tooltips showing country names and values.

Cheap Tricks for Interaction

This example shows an interactive world map colored by economic classification, with a categorical color legend. Users can pan and zoom the map using mouse or touch gestures, and hovering over a country highlights it and reveals its name and economic group via a tooltip. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering GeoJSON features, and d3.zoom for interaction. d3.scaleOrdinal with schemeSpectral maps economic categories to colors, while the legend is custom-built from SVG elements.

Cheap Tricks for Interaction

This example demonstrates interactive map exploration using D3.js version 5, visualizing world economies with a color legend and zoom functionality. The map renders countries as SVG paths via `d3.geoPath` and `geoNaturalEarth1` projection, colored by economic classification using `scaleOrdinal` with the `schemeSpectral` palette. Hovering highlights countries in red, while a zoom behavior enables pan and scale transformations. Data comes from the World Atlas TopoJSON and TSV files, with a custom color legend component showing the categorical scale.

Cheap Tricks for Interaction

A world map colored by economy type uses D3 v5's geoNaturalEarth1 projection and d3.geoPath to render country boundaries from TopoJSON data. Hovering highlights countries in red via CSS, while a reusable colorLegend function displays a clickable legend with colored circles. The map supports pan and zoom through d3.zoom, with the visualization powered by SVG rendering and a sequential spectral color scale.

Cheap Tricks for Interaction

This example displays a world map colored by each country’s economy category, using a natural Earth projection and D3’s `geoPath`. A hover effect highlights individual countries in red, while `d3.zoom` enables pan and zoom interactions that transform the entire map group. The map is rendered as SVG, with data loaded from the World Atlas TopoJSON and TSV files, and country names appear via native `<title>` tooltips. The code uses `scaleOrdinal` with `schemeCategory10` for the color scale and topojson’s `feature` method for geometry.

This interactive map shades countries by economic classification using a categorical color scale, with a clickable legend that filters the visible categories. The visualization uses d3.zoom for panning and zooming, d3.geoNaturalEarth1 with d3.geoPath for geographic projection, and SVG paths with title tooltips for hover details. Data comes from the world-atlas TopoJSON dataset joined with TSV metadata via d3.tsv and topojson.feature. The colorLegend module builds a custom SVG legend with circles and text, while CSS hover effects highlight individual countries.

Cheap Tricks for Interaction

This interactive map uses a natural Earth projection with D3’s `geoPath` and `geoNaturalEarth1` to color countries by economic classification, employing a spectral `scaleOrdinal` and a custom color legend with circles and text. Zooming is enabled via `d3.zoom`, while hovering highlights countries in red through CSS. World map geometry comes from TopoJSON’s `world-atlas`, enriched with metadata from a TSV file. The example demonstrates simple, reusable interaction patterns—tooltips via SVG `<title>` elements and a hover effect—without complex brushing or transitions.

Cheap Tricks for Interaction

This interactive map uses a natural Earth projection with a color scale to display world economies, with country names and economic classifications shown as tooltips on hover. The visualization implements zoom and pan functionality through D3's zoom behavior, while a hover effect turns countries red via CSS. Data comes from the World Atlas TopoJSON and TSV files, processed with TopoJSON's feature method, and rendered as SVG paths using d3.geoPath with d3.geoNaturalEarth1.

This example shows an interactive world map visualization that renders countries as light green polygons on a blue sphere. Hovering over any country changes its fill color to red and displays the nation’s name via a tooltip. The map is built using D3 (d3.v5) with d3.geoPath and a d3.geoNaturalEarth1 projection, combining TopoJSON and TSV data from the world-atlas package. User interaction is enhanced by d3.zoom, enabling pan and zoom transformations on the SVG group.
