Forked from Choropleth Map

This choropleth map colors countries by income group using a red-blue ordinal color scale, with a zoomable Natural Earth projection rendered as SVG paths. It loads world country boundaries from the World Atlas TopoJSON dataset and joins them to TSV metadata by ISO country code. The map includes an interactive color legend built with custom D3 selections, and uses d3.geoPath, d3.geoNaturalEarth1, d3.zoom, and d3.scaleOrdinal with schemeRdBu. Hovering highlights individual countries, and a title tooltip shows each country’s name and income group.

Choropleth Map

This choropleth map colors countries by income group using a diverging red-blue ordinal scale, with a zoomable Natural Earth projection and a color legend built from custom SVG circles. The visualization loads world country boundaries from TopoJSON and joins them to TSV metadata, then renders each nation as a styled SVG path with hover highlighting. It uses d3.geoPath, d3.geoNaturalEarth1, d3.zoom, and d3.scaleOrdinal with the schemeRdBu palette, while the legend is implemented as a reusable module.

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 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 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 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 income group using a natural Earth projection, with a categorical color scale and a clickable legend of colored circles. The map supports zooming and panning via d3.zoom, and country tooltips display name and income group. Built with D3 v5, it uses d3.geoNaturalEarth1 and d3.geoPath to render SVG paths from TopoJSON data loaded from world-atlas, while the legend is implemented as a custom reusable component.

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.
