This choropleth map colors countries by economy using a spectral ordinal scale, and includes an interactive color legend with circles and labels. The visualization renders world geography via a natural Earth projection and supports zooming and panning through d3.zoom. Data comes from the World Atlas TopoJSON and TSV files, processed with topojson.feature. The code imports individual D3 v5 modules including geoPath, geoNaturalEarth1, and scaleOrdinal, and builds the legend with a custom colorLegend function.

Fork of Choropleth Map

This choropleth map colors countries by economy using world-atlas TopoJSON data. The visualization uses d3.geoNaturalEarth1 projection with d3.geoPath to render the map, and d3.scaleOrdinal with schemeSpectral for color encoding. The color legend, built with a custom colorLegend function, displays the ordinal scale. Interactive pan and zoom is implemented via d3.zoom, and hovering highlights countries in red.

Fork of Choropleth Map

This choropleth map colors world countries by their economy classification, using a spectral ordinal color scale and a natural Earth projection. The visualization supports zooming and panning through d3.zoom, and displays a custom interactive legend built with SVG circles and text. It loads geographic and economic data from the world-atlas TopoJSON and TSV files, processing them with topojson.feature and d3.tsv. Country paths are rendered via d3.geoPath, with hover highlighting and a tooltip showing the country name and economy value.

Fork of Choropleth Map

This fork of a choropleth map colors countries by their economy classification using an ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. It renders geographic boundaries with d3.geoPath and a Natural Earth projection, and includes an interactive color legend built with custom D3 selections. The map supports zooming via d3.zoom, and country tooltips display name and economic group. Data comes from the World Atlas TopoJSON and TSV files, loaded with d3.json and d3.tsv, with hover states highlighting countries in red.

Fork of Choropleth Map

This choropleth map colors countries by economy type using a categorical ordinal scale and the spectral color scheme. It renders geographic boundaries with d3.geoPath and a natural Earth projection, while a custom color legend built with SVG circles and text shows the category mapping. Users can pan and zoom via d3.zoom. Data comes from the world-atlas TopoJSON and TSV files, with hover effects highlighting individual countries.

Fork of Fork of Choropleth Map

This choropleth map colors countries by their economy classification using a spectral color scale, with hover highlighting and a circular legend showing the categorical values. The visualization loads world topology from the world-atlas TopoJSON dataset and joins it with TSV metadata. Built with D3 v5, it uses `d3.geoNaturalEarth1` projection, `d3.geoPath` for rendering SVG paths, `d3.zoom` for pan and zoom, and `d3.scaleOrdinal` with `schemeSpectral` for color mapping.

Fork of Choropleth Map

This choropleth map colors world countries by their economy classification using a categorical ordinal color scale with the spectral scheme. The visualization renders geographic boundaries with `d3.geoPath` and the Natural Earth projection, loading TopoJSON and TSV data from the world-atlas package. Interactive zoom and tooltip features are commented out, leaving a static map with an optional color legend component defined in a separate module.

Fork of Choropleth Map

This choropleth map colors countries by economic classification using a categorical ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. The visualization renders geographic shapes with d3.geoPath and a natural Earth projection, while supporting interactive pan and zoom via d3.zoom. Data comes from the World Atlas TopoJSON and TSV files, loaded through d3.json and d3.tsv. A custom d3 color legend with circles and labels appears on the left, and hovering highlights individual countries in red.

Fork of Choropleth Map

This fork of a choropleth map visualizes countries colored by their economy category, with a legend showing the ordinal color scale. The map uses a natural Earth projection and supports zooming and panning via d3.zoom, while hovering highlights a country in red. Data from the World Atlas TopoJSON and TSV files is loaded with d3.json and d3.tsv, processed through topojson.feature, and rendered as SVG paths using d3.geoPath. The legend is built with a custom component using D3 selections.
