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.

Choropleth Map

This choropleth map colors countries by income group using an ordinal color scale built with `d3.scaleOrdinal` and `schemeSpectral`. It renders geographic boundaries with `d3.geoPath` and a Natural Earth projection, with country data sourced from the world-atlas TopoJSON dataset. Users can pan and zoom via `d3.zoom`, and hovering highlights individual countries. A custom `colorLegend` component displays the categorical color scale as an SVG legend, while 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

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

A choropleth map colors countries by their income group using a categorical ordinal color scale, with hover effects highlighting individual nations. Built with D3 v5, it renders geographic boundaries as SVG paths via `d3.geoPath` and `geoNaturalEarth1`, and loads world geometry from the world-atlas TopoJSON dataset. A custom color legend displays the categories, while zooming is enabled through `d3.zoom`. Data is processed asynchronously with Promises, merging TSV metadata with TopoJSON features.
