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.

Circles on the Map

This visualization displays the global population distribution for 2018 using sized circles positioned over a natural Earth projection map. Each circle’s radius encodes population magnitude via a square-root scale, with a corresponding size legend and a categorical color legend for missing data. The code uses D3 v5’s `geoPath`, `geoNaturalEarth1`, `zoom`, and `scaleSqrt`, rendering SVG elements. Data comes from a CSV file merged with TopoJSON world atlas geometries, and interaction includes hover tooltips showing region names and formatted population values.

Circles on a Map

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 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 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 the year 2018, using sized circles positioned on a natural Earth projection map. Countries are colored green or red to indicate whether they have available data. The circles are scaled using `scaleSqrt()` to map population values to radii. The code uses `geoPath` with `geoNaturalEarth1()` for the map projection, and loads data from a CSV file merged with TopoJSON world atlas features.

Circles on a Map

This example visualizes global population data for 2018 by coloring countries on a natural Earth projection map, with missing data highlighted in red. It uses D3 v5's `geoNaturalEarth1` and `geoPath` to render the map, `scaleSqrt` for proportional sizing, and `scaleOrdinal` with `schemeSpectral` for color encoding. The visualization supports zooming via `d3.zoom`, and tooltips appear on hover showing region names and population counts. Data comes from a CSV joined with TopoJSON world atlas geometry, loaded through `Promise.all` and processed with `topojson.feature`.

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.
