This choropleth map displays global income groups using a color scale applied to each country’s territory. The visualization employs d3.geoPath with a natural Earth projection to render the GeoJSON features, while d3.scaleOrdinal and schemeSpectral map income categories to colors. A custom color legend, built with select and merge, appears on the left. The map supports zooming via d3.zoom, and hovering highlights countries in red. Data comes from the world-atlas TopoJSON and TSV files, processed with topojson.feature.

Choropleth Map

This choropleth map depicts global income groups, coloring countries according to their income classification. Built with D3 v5 and TopoJSON, it loads world map data and country metadata, then projects it using a natural Earth projection with `d3.geoPath`. A color legend uses `scaleOrdinal` and `schemeSpectral` to map income groups to colors. The visualization supports zooming via `d3.zoom` and shows interactive hover states that display country names and income levels.

Choropleth Map

This choropleth map colors world countries by income group using a categorical color scale with a spectral scheme. The visualization supports zooming and panning through d3.zoom, with country names and income groups revealed via tooltips on hover. Built with d3.geoPath and geoNames from the world-atlas TopoJSON dataset, it renders as SVG paths over a blue sphere. A custom color legend component displays the ordinal scale’s domain, while hover interactions highlight individual countries in red.

Choropleth Map

This choropleth map colors countries by income group using an ordinal color scale with the spectral scheme. It renders geographic boundaries with d3.geoPath and a Natural Earth projection, using TopoJSON data from the world-atlas package. Hovering highlights countries in red, while a legend built with custom D3 code displays the color categories. The map supports zooming and panning through d3.zoom, and tooltips show each country’s name and income group.

Choropleth Map

This choropleth map visualizes global income groups, with each country colored according to its economic classification from the world-atlas dataset. The visualization uses a D3 v5 SVG rendering with a natural Earth projection, allowing users to pan and zoom through the interactive geoPath features. The map employs an ordinal color scale with a spectral scheme, while a custom legend (colorLegend.js) displays the categorical colors with circle markers. The data loads asynchronously from TSV and TopoJSON files via Promise.all, with country names and income group values shown as tooltips on hover.

Choropleth Map

This choropleth map visualizes countries colored by income group using a natural Earth projection. It loads world geometry from TopoJSON and joins it with TSV metadata via d3.json and d3.tsv, then renders paths with d3.geoPath. A d3.scaleOrdinal with a schemeSpectral range assigns colors, and an interactive legend built with d3-selection shows the categorical scale. The map supports zooming through d3.zoom and highlights countries on hover via CSS.

Choropleth Map

This choropleth map visualizes global income groups by coloring each country according to its income_grp property. The map uses a natural Earth projection and fills countries with colors from a spectral ordinal scale, with a background legend showing the color categories. Built with D3 v5, the code loads world geometry from TopoJSON and income data from TSV files, then renders the map as SVG paths with zoom support via d3.zoom. The color legend is implemented as a reusable component, and hovering highlights individual countries.

Choropleth map

This choropleth map colors world countries by income group using a spectral ordinal scale, with a hover effect that highlights individual country borders and a legend showing the color categories. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to render TopoJSON world-atlas data, while d3.zoom enables panning and interactive exploration. Color encoding and the legend are built with d3.scaleOrdinal and d3.schemeSpectral, with data loaded via d3.tsv and d3.json.

Choropleth Map

This choropleth map displays countries colored by their income group using a spectral color scale. The visualization renders world geography with D3 geoPath and geoNaturalEarth1 projection, featuring zoom capabilities and interactive hover effects that highlight individual countries. Data is loaded from the world-atlas package’s TSV and TopoJSON files, processed with topojson.feature, and mapped to colors using d3.scaleOrdinal and schemeSpectral. A custom color legend with circles and text labels facilitates interpretation of the income classifications.
