This choropleth map visualizes global economic data by coloring countries according to a categorical color scale. Users can click legend entries to highlight countries matching the selected category, dimming all others. Built with D3 v5, it uses `d3.geoPath` with a Natural Earth projection and `d3.scaleOrdinal` for coloring. The map loads country boundaries and economic classifications from a world-atlas TopoJSON dataset, while the interactive legend and country paths are rendered as SVG elements.

Choropleth Map

This choropleth map visualizes global economic classifications by country, coloring each nation according to its economy category. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to render the map from TopoJSON world-atlas data, with country attributes loaded from a TSV file. A color legend, constructed via `colorLegend`, displays the ordinal color scale using `d3.scaleOrdinal` and `d3.schemeSpectral`. The SVG map supports zooming via `d3.zoom`, and hovering changes a country’s fill to red.

Choropleth Map

This choropleth map visualizes global economic groupings by coloring each country according to its economy category. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries from TopoJSON data loaded from the world-atlas package. A sequential `d3.scaleOrdinal` with `schemeSpectral` assigns colors, while zooming is enabled through `d3.zoom`. Hovering highlights countries in red, and a color legend explains the ordinal categories.

Choropleth Map

This choropleth map displays global economic classifications by coloring each country according to a categorical ordinal scale derived from the `economy` property in the world-atlas dataset. The visualization loads TopoJSON and TSV data, then uses `d3.geoPath` with a natural Earth projection to render country boundaries, while a custom color legend built with SVG circles and text explains the color encoding. Users can zoom and pan via `d3.zoom`, with hover effects highlighting individual nations.

Choropleth Map

This choropleth map colors world countries by economic classification using a categorical color scale. The visualization renders geographic boundaries with SVG paths projected via `d3.geoNaturalEarth1` and `d3.geoPath`, with interactive zoom support through `d3.zoom`. A custom `colorLegend` component displays the ordinal scale’s categories as colored circles with labels. Data loads from the World Atlas TopoJSON and TSV files, with country names and economy values shown in tooltips on hover. The map uses `d3.scaleOrdinal` with `schemeSpectral` to assign distinct fills to each economic group.

Choropleth Map

This choropleth map visualizes global economic classifications by coloring each country according to its economy type. Using D3.js v5 with the `geoNaturalEarth1` projection and `geoPath` for rendering, it loads world map data from TopoJSON and TSV files containing country metadata. The color scale uses `scaleOrdinal` with `schemeSpectral` ranges, and hovering highlights a country in red while a tooltip displays the country name and economic group.

Choropleth map

A choropleth map colors world countries according to their economic classification, with a color legend that filters and highlights selected categories. Users can click legend entries to dim non-matching countries and intensify the selected region. Built with D3.js, the visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to project TopoJSON data from the world-atlas package, while `d3.scaleOrdinal` with `d3.schemeSpectral` assigns colors. Interactive zoom via `d3.zoom` and SVG rendering provide the map interface.

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.
