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

A choropleth map colors world countries by income group using an ordinal color scale with a spectral scheme. The visualization renders geographic boundaries via TopoJSON data and the d3.geoPath projection, with a legend displaying color categories. Interactive zooming is enabled through d3.zoom, and hovering highlights individual countries. Data comes from the world-atlas and visionscarto-world-atlas packages.

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 colors world countries by income group, using a spectral color scale with a legend showing the categorical ranges. It renders country boundaries as SVG paths via the `d3.geoPath` and `d3.geoNaturalEarth1` projections, with a zoom interaction applied through `d3.zoom`. Data comes from the `world-atlas` TopoJSON and TSV files, processed with `topojson.feature` to merge attributes. Hovering highlights a country in red and displays its name and income group in a tooltip.

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 colors countries by their income group using a categorical color scale based on d3.scaleOrdinal and d3.schemeSpectral. It renders geographic boundaries with d3.geoPath and a natural Earth projection, loading TopoJSON and TSV data from the world-atlas package. The visualization includes an interactive color legend built with reusable D3 code, supports zooming via d3.zoom, and highlights countries on hover with a red fill.

Choropleth Map

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

A choropleth map colors countries by income group using an ordinal color scale with a spectral scheme, drawing each nation with `d3.geoPath` and a Natural Earth projection. The visualization supports zooming via `d3.zoom` and includes a custom color legend rendered with SVG circles and text. Country names and income data come from TopoJSON and TSV files loaded from the world-atlas package. Hovering over a country reveals its name and income group in a tooltip.

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.
