This choropleth map colors countries by their economy category using a blue ordinal scale, with a hover tooltip showing the country name and economy value. The visualization projects geographic data with `d3.geoNaturalEarth1` and renders features via `d3.geoPath`. It loads country boundaries from TopoJSON and names from TSV, then applies `d3.zoom` for panning and scaling. A custom `colorLegend` component displays the color scale with circles and labels in SVG.

Choropleth Map

This choropleth map colors countries by their economy type using a categorical color scale, with a legend showing each category. It renders world geography as SVG paths via `d3.geoPath` and the Natural Earth projection, while `d3.zoom` enables panning and zooming. The code loads TopoJSON and TSV data from the world-atlas package, mapping country IDs to economy labels, and uses `d3.scaleOrdinal` with `schemeSpectral`. Hovering highlights a country in red.

Choropleth Map

This choropleth map colors countries by their economy classification, with a color legend and tooltips showing each country’s name and category. The visualization uses a natural Earth projection rendered as SVG paths via d3.geoPath, while TopoJSON and TSV data from the world-atlas package are loaded asynchronously. Users can pan and zoom the map using d3.zoom, and hovering highlights individual countries in red. The color scale uses d3.scaleOrdinal with a spectral scheme, and an interactive legend is built from custom d3 selections.

Choropleth Map

This choropleth map colors world countries by their economy category using an ordinal color scale with a spectral scheme. The visualization supports zooming and panning through d3.zoom, while d3.geoNaturalEarth1 and d3.geoPath render the geographic features from TopoJSON world-atlas data joined with TSV country metadata. Countries display a tooltip with their name and economy value on hover, and a custom color legend built with SVG circles and text shows the category mapping.

Choropleth Map

A choropleth map colors each country by its economy classification using an ordinal color scale with a spectral palette. The visualization supports pan and zoom via d3.zoom, and renders geographic features with d3.geoPath and a Natural Earth projection. A custom color legend component displays the categorical scale, while data is loaded from the World Atlas TopoJSON and TSV files, with tooltips showing country names and economy values on hover.

Choropleth Map

This choropleth map colors countries by their economy category using a sequential spectral color scale. It renders world geography as SVG paths via the `d3.geoPath` and `d3.geoNaturalEarth1` projection, with zoom support through `d3.zoom`. Country names and values appear as tooltips, and a custom `colorLegend` component displays the ordinal scale. The data is loaded from a TopoJSON world atlas and a TSV mapping country IDs to metadata. Hovering highlights countries in red.

Choropleth Map

A choropleth map colors countries by their economy category using an ordinal color scale derived from the World Atlas TopoJSON dataset, which is joined with tab-separated metadata. The visualization uses d3.geoPath with a Natural Earth projection and supports zooming via d3.zoom. A custom color legend, built with SVG circles and text, displays the color scale categories. Countries are interactive, showing their name and economy group in a tooltip on hover, with a red highlight effect.

Choropleth Map

This choropleth map colors world countries by their economy category using an ordinal color scale with a spectral scheme, and displays a color legend with clickable circles. It renders geographic boundaries with antialiased SVG paths via `d3.geoPath` and the Natural Earth projection, while loading data from the world-atlas package (TSV metadata and TopoJSON geometries) and processing it with `topojson.feature`. Hovering highlights a country in red, and the map supports zooming through the `d3.zoom` interaction.
