Forked from Circles on a 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 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 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 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 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 countries according to their income group, using a spectral color scale with a natural Earth projection. The visualization includes a color legend with circles and labels, and supports zooming via d3.zoom. Data is loaded from a TSV file and TopoJSON world atlas using Promise.all, then rendered as SVG paths with d3.geoPath. Hovering highlights countries in red, and tooltips show country names and income group values.

Choropleth Map

This choropleth map visualizes the income group of each country using a sequential color scale, with hover interactions highlighting individual nations. Built with D3.js (v5) and TopoJSON, it projects world geography via the Natural Earth projection and renders country boundaries as SVG paths. The color legend, generated with custom code, displays ordinal color swatches and labels. Data is sourced from the world-atlas package, merging TSV attributes with TopoJSON geometry.
