Choropleth Map

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 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 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

This choropleth map colors countries by economic group, drawing from world-atlas TopoJSON and TSV data joined by country ID. The visualization renders the map with D3’s `geoNaturalEarth1` projection and `geoPath` generator, while an ordinal color scale from `schemeSpectral` assigns shades to each group. A custom color legend displays every category with circles and labels, and users can zoom and pan via D3’s `zoom` event, which updates the group’s transform. Hovering a country highlights it in red and shows its name and economy in a tooltip.

Choropleth Map

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, built with D3.js, visualizes global economic classifications by country. It uses a spectral color scale from the `schemeSpectral` range, with countries colored according to their economy attribute. Users can click legend items to highlight specific economic groups, which dims non-matching countries. The map projects geographic features using `geoNaturalEarth1` with `geoPath`, and data is loaded from the world-atlas TopoJSON and TSV files.

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.
