This visualization displays global population data for 2018 as circles on a natural Earth projection map. Countries without data are shown in one color, while those with data use a square-root size scale to encode population magnitude. The code uses d3.geoPath for map rendering, d3.geoCentroid for positioning, and d3.scaleSqrt for circle sizing. Data comes from a CSV file joined with TopoJSON world atlas features, with interactive zoom via the d3.zoom API.

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 for 2018 by projecting circles onto a natural Earth map, with circle area proportional to each country’s population. Users can pan and zoom, and hovering reveals country names and population values. The code uses `d3.geoNaturalEarth1`, `d3.geoPath`, `d3.geoCentroid`, and `d3.zoom` for the map and interactions. Data comes from a CSV joined with TopoJSON world atlas geometries, and circles are rendered as SVG elements. A square-root scale controls circle sizes, accompanied by custom size and color legends.

Circles on a Map

This visualization uses a natural Earth projection to display global population data for 2018, with each country represented by a circle whose area is proportional to its population. The map supports pan and zoom interactions, and hovering over a country reveals its population through a tooltip. Built with D3.js, it uses `d3.geoPath` for map rendering, `d3.scaleSqrt` for the size scaling, and custom legends to explain both the color scheme and circle sizes. Population data comes from a CSV file joined to a TopoJSON world atlas.

Circles on a Map

This visualization displays global population data for 2018, with each country represented by a circle whose area corresponds to population size. Pan and zoom interactions use d3.zoom. The map is rendered with d3.geoNaturalEarth1 and d3.geoPath, while circle radii are scaled by d3.scaleSqrt. Hovering reveals country names and population counts via SVG title elements. Data comes from a CSV joined with TopoJSON world atlas geometry, and a d3.scaleOrdinal color legend and size legend are included.

Circles on a Map

This visualization displays global population data for 2018 using circles overlaid on a natural Earth projection map. The area of each circle is proportional to the country’s population, with missing data highlighted in red. Users can pan and zoom via d3.zoom, and hover over countries to see exact population figures. Built with D3 v5, it uses d3.geoPath and d3.geoNaturalEarth1 for map rendering, d3.scaleSqrt for circle sizing, and TopoJSON for world boundaries, with population data joined from a CSV file.

Circles on a Map

This visualization displays global population data for 2018 using scaled circles positioned at country centroids on a natural Earth projection map. Circle area encodes population magnitude, while hovering reveals exact population figures and regional names. The map supports pan and zoom interactions through d3.zoom. Built with d3.geoNaturalEarth1 and d3.geoPath for map rendering, it uses d3.scaleSqrt for circle sizing and d3.scaleOrdinal with a spectral scheme for the categorical color legend. Population data comes from a CSV file processed alongside TopoJSON world boundaries.

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 map visualization displays global population data for 2018 using circles sized by population magnitude and colored by data availability. The geographic map is rendered with D3’s `geoNaturalEarth1` projection and `geoPath`, while circle radii are scaled with `scaleSqrt`. The code uses TopoJSON world atlas data merged with CSV population figures. A size legend and a color legend are drawn as SVG elements, and zoom interaction is enabled via `d3.zoom`. Countries missing data appear red, while those with values are green.
