This example visualizes global population data by drawing semi-transparent circles on a natural Earth projection map. Each circle is positioned at a country's centroid using `d3.geoCentroid` and scaled in radius according to 2018 population figures via `d3.scaleSqrt`. Countries without data appear in light red, while others are gray. The visualization includes an interactive zoom feature using `d3.zoom` and two legends: a color legend for economy types and a size legend for population, built with custom React components and rendered as SVG. Data is loaded from CSV and TopoJSON files using `d3.csv` and `d3.json`.

Circles on a Map

This visualization displays global population data for 2018 as colored circles positioned on a natural Earth projection map. Countries are shaded with a spectral color scale, while circle size encodes population magnitude using a square-root scale. The code loads CSV and TopoJSON data with d3.csv and d3.json, then renders the map using d3.geoPath and d3.geoNaturalEarth1, with circles placed via d3.geoCentroid and scaled by d3.scaleSqrt.

Circles on a Map

This example visualizes global population data on an interactive world map, with circular markers sized proportionally to each country’s 2018 population via a square-root scale. Hovering over a country reveals its exact population in a tooltip. The map uses d3.geoNaturalEarth1 and d3.geoPath for geographic projection and rendering, while d3.zoom enables pan and zoom. Circles are positioned using d3.geoCentroid, and data merges CSV population figures with TopoJSON world boundaries using topojson.feature, with legends built through custom colorLegend and sizeLegend modules.

Circles on a map

This map visualizes global population data for 2018, overlaying semi-transparent circles on a natural Earth projection. Countries without data appear in light red, while those with values are gray and display proportional circles positioned at their centroids. The visualization uses D3 v5 with `geoNaturalEarth1`, `geoPath`, `geoCentroid`, and `scaleSqrt` for sizing, plus `topojson` for world geometry. Hovering reveals a tooltip with the region name and formatted population. A size legend explains circle scaling, and zooming is enabled via `d3.zoom`.

The circles are sized using `d3.scaleSqrt` based on 2018 population figures, and hovering over countries reveals their population via a tooltip. The visualization uses `d3.geoPath` with `geoNaturalEarth1` for map projection, `d3.zoom` for panning and zooming, and includes both a color legend and a size legend built from `d3.scaleOrdinal` and `d3.scaleSqrt`. Data is loaded from a CSV file and TopoJSON world atlas using `d3.csv` and `d3.json`.

Circles on a Map with D3.js!

This visualization displays world population estimates for 2018 as semi-transparent circles positioned at country centroids on a Natural Earth projection map. Circle size encodes population magnitude, while a color legend categorizes countries by income group. The code uses D3.js v5 with `d3.geoNaturalEarth1`, `d3.geoPath`, `d3.geoCentroid`, `d3.scaleSqrt`, and `d3.scaleOrdinal`, plus TopoJSON data from world-atlas and UN population CSV data. Interactive zooming is implemented via `d3.zoom`, with SVG rendering and custom color and size legends.

Circles on a Map

This visualization displays global population data for 2018, using a natural Earth projection with circles sized by population at each country’s centroid. Countries with missing data appear in light red, while mapped regions are gray and populating circles use a teal fill. The map supports zooming via d3.zoom, and the code employs d3.geoPath for rendering country boundaries, d3.scaleSqrt for circle sizing, and d3.scaleOrdinal with a spectral scheme for the color legend. Data comes from a CSV file joined to TopoJSON world geometries, with both size and color legends implemented as reusable D3 modules.

Circles on a Map

This visualization displays global population data on a natural Earth projection map. Countries with missing data appear in red, while the rest are gray, and semi-transparent circles sized by population are placed at country centroids. A custom legend shows the population scale. The code uses D3 v5 functions like `geoPath`, `geoCentroid`, `geoNaturalEarth1`, and `scaleSqrt`, along with a custom `sizeLegend` for the bubble chart. Data is loaded from a CSV file and a TopoJSON world atlas.

Circles on a map

This visualization displays global population data for 2018 using circles overlaid on a natural Earth projection map. The circles, sized with a square root scale, represent population magnitudes, while a legend explains the scaling. A color legend and interactive zooming are also included. The code uses D3 v5 APIs like `geoPath`, `geoNaturalEarth1`, `scaleSqrt`, and `topojson.feature`, with data loaded from a CSV file and a TopoJSON world atlas. The visualization is rendered as an SVG within a React framework.
