Forked from Let's make a map

This choropleth map colors countries by economic classification, with a hover effect highlighting individual nations and a legend showing the categorical color scale. The visualization renders world geography using `d3.geoPath` with a Natural Earth projection, while `d3.zoom` enables pan and zoom interaction. Data loads from the world-atlas TopoJSON and TSV files, merged by country ID, and the color scale uses `d3.scaleOrdinal` with `schemeSpectral` ranges. The legend is built as a reusable component with `selection.enter` and `merge` patterns.

Choropleth Map

This choropleth map colors countries by their economic classification using a spectral color scale, with hover highlighting and zoom/pan enabled via d3.zoom. The visualization loads world geometry from TopoJSON and joins it with tab-separated country metadata from the world-atlas dataset. It renders geographic paths with d3.geoPath and a Natural Earth projection, while a custom color legend displays ordinal color domains using SVG circles and text.

Choropleth Map

This choropleth map visualizes countries colored by their economic classification, using a spectral color scale to distinguish categories. The map renders geographic boundaries as SVG paths via `d3.geoPath` and a Natural Earth projection. Data is loaded from the World Atlas TopoJSON and TSV files, merged by country ID, then assigned to the `d3.scaleOrdinal` color scale. A custom legend shows color swatches with labels, and hovering highlights individual countries in red. Interaction includes zoom and pan through the `d3.zoom` event, which applies an SVG transform.

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.

Choropleth Map

This choropleth map colors countries by their economic classification using a categorical ordinal color scale from `d3.scaleOrdinal` with the `schemeSpectral` palette. It renders world geography with `d3.geoPath` and a Natural Earth projection, loading TopoJSON country boundaries and TSV metadata from the world-atlas package. A custom color legend built with D3 selections appears alongside the map, while `d3.zoom` enables panning and zooming. The visualization uses SVG elements and includes hover effects that highlight individual countries.

Choropleth Map

This choropleth map colors countries by economic group using a spectral color scale, with hover effects that highlight individual nations. The visualization uses D3.js (v5) to load world map data from TopoJSON and TSV files, projecting geographic coordinates with d3.geoNaturalEarth1 and rendering paths via d3.geoPath. A custom color legend with circles and text labels is built using D3 selections, while zooming is enabled through d3.zoom. The map data comes from the world-atlas package, and SVG is used for all rendering.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale with a spectral palette. The visualization includes a custom SVG color legend showing category colors and labels. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering, and applies zoom interactions. The map loads TopoJSON data from world-atlas and joins it with TSV metadata to assign country properties. Hovering highlights individual countries 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

A choropleth map colors world countries by economic classification using an ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral, with a legend rendered via a custom colourLegend component. Geographic shapes are drawn with d3.geoPath and a Natural Earth projection, while data loads from World Atlas TopoJSON and TSV files. Hovering highlights countries, and d3.zoom enables panning and zooming with animated transitions on the legend circles.
