Choropleth Map

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.

Choropleth Map

This choropleth map colors countries by their economy classification using an ordinal color scale with a spectral scheme. The geographic data comes from the world-atlas TopoJSON dataset, which is processed with topojson.feature and joined to TSV metadata. A natural Earth projection renders the map via d3.geoPath, while d3.zoom enables panning and zooming. Hovering highlights countries in red, and a custom color legend displays the color scale with circles and text labels.

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 countries by their economy classification using a categorical color scale derived from d3.scaleOrdinal and d3.schemeSpectral. It loads GeoJSON from TopoJSON world-atlas data and merges it with TSV metadata, then renders paths via d3.geoPath with a Natural Earth projection. Hovering highlights countries in red, while a custom color legend built with reusable D3 code displays the ordinal categories. Zoom and pan are enabled through d3.zoom, and the SVG output includes tooltips showing country names and economy values.

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 world countries by their economy classification, using a categorical ordinal color scale. The visualization loads geographic data from the world-atlas TopoJSON and TSV files, then renders the map via d3.geoPath with a natural Earth projection. Zooming is enabled through d3.zoom, and countries highlight red on hover. A custom color legend displays the economy categories as colored circles, while the map also shows a blue sphere background. The code uses d3.scaleOrdinal with schemeSpectral ranges to assign colors.

Choropleth Map

A choropleth map colors countries by their economy classification using an ordinal color scale with a spectral scheme. The visualization loads geographic data from the World Atlas TopoJSON and TSV files, projecting it with d3.geoNaturalEarth1 and rendering paths via d3.geoPath. Hovering highlights a country in red, while a custom color legend component displays the categorical ranges. Zooming is enabled through d3.zoom, and the map includes a static sphere background.
