This interactive visualization displays global population estimates for 2018 as proportional circles centered on each country, overlaid on a natural Earth projection map. The map uses D3 v5’s `geoPath` and `geoNaturalEarth1`, while circle radii are scaled with `scaleSqrt` based on UN population data. A zoom behavior lets viewers pan and scale the map, and a custom size legend with tick labels explains the scaling. Countries without data appear in a distinct color, and hovering reveals country names and population figures via SVG `<title>` elements.

Circles on a Map

This visualization displays global population estimates for 2018 as proportional circles positioned at country centroids on a natural Earth projection map. Country boundaries are rendered as paths using d3.geoPath, while circle radii scale with population via d3.scaleSqrt. Two legends—a size legend and a color legend—communicate the quantitative mapping, with colors assigned through d3.scaleOrdinal. The map supports zooming through d3.zoom, and data comes from United Nations population estimates loaded as CSV and TopoJSON, processed with topojson.feature.

Circles on a Map

This visualization displays global population by country in 2018, with circles sized proportionally to population counts overlaid on a natural Earth projection map. The map supports pan and zoom interactions, and hovering over countries reveals population data or missing-data indicators. Built with D3 v5, the example uses `d3.geoPath` for map rendering, `d3.geoNaturalEarth1` for projection, `d3.zoom` for interaction, and `d3.scaleSqrt` for circle sizing, while styling and legend components are defined in separate JavaScript modules. Population data comes from a UN estimates CSV, with country boundaries from a TopoJSON world atlas.

Circles on A Map

This visualization displays global population estimates for 2018 by drawing semi-transparent circles on a natural Earth projection map, with each circle positioned at a country's centroid and sized proportionally to its population. The map also includes a size legend and color legend for reference. Built with D3 v5, it uses `d3.geoNaturalEarth1` and `d3.geoPath` for map rendering, `d3.scaleSqrt` for circle sizing, and `d3.zoom` for interactivity. Population data comes from a UN dataset, with geographic boundaries from TopoJSON, and all elements are rendered as SVG.

Circles on a Map

This visualization displays global population estimates for 2018, using a natural Earth projection to map countries. The map uses semi-transparent circles sized by population magnitude, while a color legend and size legend clarify the encoding. Built with D3 v5, the code leverages `geoNaturalEarth1` and `geoPath` for map projection, `scaleSqrt` for circle sizing, and `scaleOrdinal` for the color scheme. Data is sourced from UN population estimates joined with a TopoJSON world atlas. A tooltip on each country provides its name and population count, with missing data highlighted in light red.

Circles on a map

This map visualizes global population estimates for 2018 using proportional circles overlaid on a geographic projection of the world. The visualization layers semi-transparent teal circles at each country’s centroid, with circle radius scaled by the square root of population via a legend. It employs D3’s `geoNaturalEarth1` projection, `geoPath`, and `geoCentroid` for map geometry, alongside `scaleSqrt` for sizing and `scaleOrdinal` for color. Data combines UN population CSV estimates with TopoJSON country boundaries, processed through local modules `loadAndProcessData` and `sizeLegend`.

Circles on a Map

This visualization displays global population data for 2018 using proportional circles positioned at country centroids on a natural Earth projection. The map uses d3.geoPath and d3.geoCentroid to render countries and place scaled symbols, with d3.scaleSqrt determining circle radii. Hovering reveals country names and population values via SVG titles. Pan and zoom are enabled through d3.zoom, while a d3.scaleSqrt-based legend indicates population magnitudes. Data comes from a CSV file of UN population estimates joined with TopoJSON world geometry, rendered as SVG with color coding for missing values.

Circles on a Map

This map visualizes global population estimates for 2018 by projecting country centroids onto a natural Earth projection. Circles sized proportionally to population via a square-root scale are placed at each centroid, while uniform circles represent countries lacking data. The visualization uses D3.js APIs including `geoPath`, `geoCentroid`, `geoNaturalEarth1`, `scaleSqrt`, and `scaleOrdinal`, rendering with SVG. Population data comes from a CSV of UN estimates, and country shapes from 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 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.
