This example presents a choropleth map of the world, coloring each country according to its economic classification. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1()` and renders SVG paths with `d3.geoPath`. Country boundaries are stroked in black, and hovering turns a country black. The code merges TopoJSON geometry with TSV data, and colors are assigned using `d3.scaleOrdinal` with a reversed `d3.schemeSpectral` palette, where the legend is not shown. Data is sourced from the `world-atlas` package and a custom TopoJSON file.

This example shows a choropleth map of world countries colored by their economy category, using a spectral color scale. The visualization renders SVG paths via d3.geoPath with a natural Earth projection, while d3.zoom enables panning and zooming. A custom color legend component displays ordinal values with circles and text, and hovering over any country highlights it in red. Data comes from the world-atlas TopoJSON and TSV files, with countries styled using CSS stroke and fill properties.

Untitled

This example displays a world choropleth map colored by each country’s economy category, with an interactive legend that filters and highlights selected categories. It uses d3.geoPath and d3.geoNaturalEarth1 for geographic rendering from TopoJSON data loaded via topojson.feature, with d3.scaleOrdinal and schemeSpectral mapping categories to colors. The legend and map respond to clicks, adjusting opacity and stroke widths, while d3.zoom enables panning and zooming.

This visualization displays a world map using a Natural Earth projection, with each country rendered as a white SVG path with green borders using D3 v4’s `d3.geoPath` and TopoJSON data from `world-110m.json`. Country names from `world-country-names.csv` are joined to the geometry via their IDs. Hovering over a country changes its fill to grey, thickens its stroke, and shows a tooltip with the country’s name that follows the mouse cursor.

Map

This example visualizes world countries as a choropleth-style map, coloring each country green with white borders on a dark blue spherical backdrop. The map renders as SVG using D3.js with a Natural Earth projection via `d3.geoNaturalEarth1`, and country boundaries are generated through `d3.geoPath`. Geographic data loads from the world-atlas TopoJSON file (countries-110m.json), which is converted to GeoJSON using the `feature` function from the topojson library. Hovering a country changes its fill to red, and each country includes a title tooltip displaying its name.

A choropleth map colors countries according to the number of students per country, with a sequential red color scale and a legend showing count ranges. The visualization uses D3 v5’s `d3.geoMercator` projection and `d3.geoPath` to render world topology from the World Atlas TopoJSON, while data from a TSV file is joined to country features. Country boundaries are styled with white strokes, and hovering highlights the selected country.

Choropleth Map.js!

This example shows a choropleth map of the world’s countries, colored by economic classification using a spectral color scale. The map renders as SVG and supports mouse hover highlighting, which changes the fill of individual countries to dark green. It loads geographic data from the world-atlas TopoJSON and matches it with country names and economy values from a TSV file. The visualization uses d3.geoPath with a d3.geoNaturalEarth1 projection, applies a d3.scaleOrdinal for colors, and enables pan and zoom through d3.zoom.

Choropleth Map

A choropleth map colors countries by economic grouping, with a legend of colored circles and a natural Earth projection. It uses d3.geoPath, d3.geoNaturalEarth1, d3.scaleOrdinal with schemeSpectral, and d3.zoom for panning. The code loads world atlas TopoJSON and TSV data via topojson.feature, rendering country paths as SVG with hover highlighting.

Choropleth Map

A choropleth map colors countries according to their economy type, with a custom ordinal color legend and hover interactions that highlight each nation. The visualization renders an SVG world map using a natural Earth projection via `d3.geoPath` and `d3.geoNaturalEarth1`, while supporting pan and zoom through `d3.zoom`. Data comes from the World Atlas TopoJSON and TSV datasets, processed with `topojson.feature` and loaded asynchronously. The color scale uses `d3.scaleOrdinal` with `d3.schemeSpectral`, and the legend is built with custom D3 enter/merge/exit selections.
