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

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 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 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.

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

A choropleth map colors world countries according to their income group, using a spectral color scale. The map is rendered as an SVG with a natural Earth projection, and hovering highlights a country in red. Built with d3.v5 and topojson, it loads geographic data from the World Atlas TopoJSON files alongside a TSV table of income classifications. The code uses `d3.geoPath`, `d3.geoNaturalEarth1`, `d3.zoom`, and a custom `colorLegend` component that maps ordinal color values to circles and labels.

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 according to their income group, using a spectral color scale with a clickable legend that displays the categorical values. The map is rendered with SVG paths generated by `d3.geoPath` and a `geoNaturalEarth1` projection, with zooming enabled via `d3.zoom`. Geographic data comes from the World Atlas TopoJSON, joined with country names from a TSV file. The color legend is built with `scaleOrdinal` and custom `colorLegend` functions.
