Choropleth World Map w/ D3.js

Choropleth map with D3.js!

This choropleth map visualizes world countries colored by income group using D3.js. The map uses a natural Earth projection via `d3.geoPath` and `geoNaturalEarth1`, with country boundaries loaded from TopoJSON world-atlas data and income classifications joined from a TSV file. A color legend built with `scaleOrdinal` and `schemeSpectral` displays the categorical color scale. Interactive zooming is implemented 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 colors world countries by income group, using a spectral color scale with an accompanying legend. The visualization is built with D3.js, using `d3.geoPath` and `d3.geoNaturalEarth1` for map projection and rendering, and `zooming` via `d3.zoom` event handling. Country data comes from the `world-atlas` package, with income group information joined from a TSV file, and the map supports hover highlighting.

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 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.

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.
