Choropleth Map

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 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 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 - Modular

A choropleth map colors world countries by income group, with a categorical color legend and zoom/pan support. Built with D3 v5, it uses `d3.geoNaturalEarth1` and `d3.geoPath` to project TopoJSON world data from the world-atlas package, while `d3.scaleOrdinal` assigns spectral colors. Interactive hovering highlights country borders, and the legend is rendered as an SVG component.

Choropleth Map

A choropleth map colors countries by economic income group using an ordinal color scale. The visualization uses D3 v5 with d3.geoPath and a Natural Earth projection to render TopoJSON world data loaded from the world-atlas package. Users can zoom and pan via d3.zoom, and hovering highlights individual countries. A custom color legend component displays the category colors and labels, with interactivity handled through SVG selections.

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.
