Choropleth map

Choropleth map

A choropleth map colors countries by income group using a categorical color scale, with a hover effect that turns each country red and a tooltip showing the country name and income group. The visualization loads geographic data from the World Atlas TopoJSON and TSV files, processes it with `topojson.feature` and `d3.tsv`, and projects it using `d3.geoNaturalEarth1` and `d3.geoPath`. A custom legend built with `d3.scaleOrdinal` and `schemeSpectral` renders interactive color swatches, while `d3.zoom` enables panning and zooming on the SVG map.

Choropleth Map

This choropleth map visualizes global income groups by coloring each country according to its `income_grp` attribute, using a spectral color scale (`d3.schemeSpectral`). The map shows a natural Earth projection rendered with `d3.geoPath`, with hover interactions highlighting countries in red. Built with React and D3 v6, it loads world boundary data from the `world-atlas` package via TopoJSON and TSV files, and includes a custom color legend component. The visualization supports zooming through a zoom behavior API.

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 example displays a choropleth map of the world, coloring each country according to its income group using a categorical color scale. The visualization loads geographic data from the World Atlas TopoJSON and TSV files, projecting it with `d3.geoNaturalEarth1` and rendering paths via `d3.geoPath`. A custom legend component uses D3 selections to show color categories. The map supports zoom and pan through `d3.zoom`, and hovering over a country highlights it in red while a tooltip reveals its name and income group.

Choropleth Map

This choropleth map displays global income groups using a color scale applied to each country’s territory. The visualization employs d3.geoPath with a natural Earth projection to render the GeoJSON features, while d3.scaleOrdinal and schemeSpectral map income categories to colors. A custom color legend, built with select and merge, appears on the left. The map supports zooming via d3.zoom, and hovering highlights countries in red. Data comes from the world-atlas TopoJSON and TSV files, processed with topojson.feature.

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 depicts global income groups, coloring countries according to their income classification. Built with D3 v5 and TopoJSON, it loads world map data and country metadata, then projects it using a natural Earth projection with `d3.geoPath`. A color legend uses `scaleOrdinal` and `schemeSpectral` to map income groups to colors. The visualization supports zooming via `d3.zoom` and shows interactive hover states that display country names and income levels.

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.
