This choropleth map visualizes global income groups, coloring each country according to its income_grp category with a spectral color scale. The map uses a natural Earth projection and supports zooming via the zoom API, while a legend explains the color categories. The visualization loads world country geometries from the world-atlas TopoJSON and TSV datasets, processes them with topojson.feature, and renders the paths using d3.geoPath. Hovering highlights a country in gray and reveals a tooltip with its name and income group.

Swanton Choropleth Map

This choropleth map visualizes global income groups by country, coloring each nation according to its income classification on a natural Earth projection. The map supports interactive zooming and panning, with a legend displaying the categorical color scale. Built with D3 v5, it uses `geoPath` and `geoNaturalEarth1` for map projection, `scaleOrdinal` with `schemeSpectral` for colors, and loads country boundaries from the world-atlas TopoJSON dataset, joining income data from a TSV file. Hovering reveals country names and income groups via SVG titles.

Swanton's Travels

A choropleth map displays world countries colored by income group, with a color legend for filtering. Clicking a country highlights it and dims all others; clicking again resets. The map uses D3's `geoNaturalEarth1` projection with `geoPath` for rendering shapes, and supports zooming via the `zoom` event. Data is loaded from a CSV of travelers and a TopoJSON world atlas, processed with `topojson.feature`. An ordinal spectral color scale maps economy categories.

Choropleth Map

This choropleth map visualizes global income groups by coloring each country according to its income_grp property. The map uses a natural Earth projection and fills countries with colors from a spectral ordinal scale, with a background legend showing the color categories. Built with D3 v5, the code loads world geometry from TopoJSON and income data from TSV files, then renders the map as SVG paths with zoom support via d3.zoom. The color legend is implemented as a reusable component, and hovering highlights individual countries.

Choropleth Map

This choropleth map displays global income groups using a color scale applied to each country’s territory. The visualization employs d3.geoPath with a natural Earth projection to render the GeoJSON features, while d3.scaleOrdinal and schemeSpectral map income categories to colors. A custom color legend, built with select and merge, appears on the left. The map supports zooming via d3.zoom, and hovering highlights countries in red. Data comes from the world-atlas TopoJSON and TSV files, processed with topojson.feature.

Swanton Choropleth Map

This choropleth map uses color to depict the economic classification of each country, rendered as an SVG via D3's `geoPath` and `geoNaturalEarth1` projection. Hovering a country turns it gray and reveals its name and economy in a tooltip. The map loads world geography and tabular data from the world-atlas package, and displays a color legend built with custom `colorLegend` logic. The visualization supports zooming and panning through D3's `zoom` component.

Choropleth Map

This choropleth map colors world countries by income group using an ordinal color scale with a spectral scheme. The visualization supports pan and zoom interactions through d3.zoom, while d3.geoPath and a Natural Earth projection render the geographic shapes. A custom color legend component displays the categorical colors with labeled circles. Country names and income groups appear as tooltips via SVG title elements, with data loaded from the world-atlas TopoJSON and TSV files.

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 visualizes global income groups, with each country colored according to its economic classification from the world-atlas dataset. The visualization uses a D3 v5 SVG rendering with a natural Earth projection, allowing users to pan and zoom through the interactive geoPath features. The map employs an ordinal color scale with a spectral scheme, while a custom legend (colorLegend.js) displays the categorical colors with circle markers. The data loads asynchronously from TSV and TopoJSON files via Promise.all, with country names and income group values shown as tooltips on hover.
