This choropleth map colors countries by economic classification using a categorical ordinal scale with the Spectral scheme. It loads world geometry from TopoJSON and joins it with TSV metadata, then renders the map with d3.geoPath and a Natural Earth projection. The visualization includes an interactive color legend built with custom SVG components, and supports zooming and panning through d3.zoom. Hovering highlights individual countries in red, and tooltips display each country’s name and economic group.

Choropleth Map

A choropleth map colors countries by their economic classification, with a color legend showing ordinal categories from the Spectral scheme. The visualization loads world geometry from TopoJSON and joins it with tabular data from a TSV file. Using d3.geoPath with a geoNaturalEarth1 projection, it renders SVG paths that support zooming via d3.zoom. Hovering highlights individual countries, while a custom colorLegend component displays the color scale with circles and text labels.

Choropleth Map

A choropleth map colors countries by their economic classification using an ordinal color scale with a spectral scheme. The visualization loads world geometry from TopoJSON and country metadata from TSV, joining them by ISO numeric codes, and renders with D3’s `geoNaturalEarth1` projection and `geoPath`. A custom `colorLegend` displays the scale, while zooming and panning are enabled via `d3.zoom`. Hovering highlights countries, and tooltips reveal name and economy class.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale with a spectral scheme. Hovering highlights a country in red, and the map includes a legend showing color categories. Built with D3 v5, it uses `geoPath` with the Natural Earth projection and loads geographic data from the world-atlas TopoJSON and TSV files. The visualization supports zooming via D3's zoom event and renders as an SVG.

Choropleth Map

A choropleth map colors countries by economic category using an ordinal color scale with a spectral palette. The visualization loads world geometry and country metadata from the world-atlas TopoJSON and TSV files, rendering paths with `d3.geoPath` and a Natural Earth projection. Users can pan and zoom via `d3.zoom`, while a custom legend built with D3 selections displays color categories as circles and text. Hovering highlights a country in red, and tooltips show each nation's name and economy type.

Choropleth Map

This choropleth map colors world countries by economic classification using a categorical ordinal scale with a spectral color scheme. Users can zoom and pan the natural Earth projection, while a custom color legend displays the category colors and labels. The visualization loads geographic and metadata from the world-atlas TopoJSON and TSV files, rendering paths via d3.geoPath and enabling interaction through d3.zoom. Hovering highlights individual countries, and the legend is built with reusable d3 selections.

Choropleth Map

This choropleth map colors countries by economic classification, with a color legend and zooming and panning via d3.zoom. It loads world geometry from TopoJSON and country names from TSV data, joining them by ID. The map uses a natural Earth projection via d3.geoNaturalEarth1 and d3.geoPath, with an ordinal color scale based on d3.scaleOrdinal and a spectral scheme. Hovering highlights countries, and a custom color legend is built with reusable SVG components.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale with a spectral palette. The visualization includes a custom SVG color legend showing category colors and labels. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering, and applies zoom interactions. The map loads TopoJSON data from world-atlas and joins it with TSV metadata to assign country properties. Hovering highlights individual countries in red.
