This visualization uses a natural Earth projection to display the population of each country as a circle, where the circle's area is proportional to the country's 2018 population. Users can pan and zoom the map, and hovering over a country reveals its name and population in a tooltip. The D3 code loads data from a UN CSV and a TopoJSON world atlas, computing circle sizes with `d3.scaleSqrt` and rendering the map using `d3.geoPath`. A size legend and a color legend for missing data are also included.

AI-generated description

Visualizing population by country using circles on a map! The area of each circle corresponds to the population of the country it represents. You can also pan & zoom, and hover over each country for more information.

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 the population of each country as a circle on a natural Earth projection map, with the circle’s area proportional to the 2018 population data. Hovering over a country reveals its name and population, while pan and zoom are enabled. The map is rendered as SVG using `d3.geoPath` with a `geoNaturalEarth1` projection, and population data is joined from a CSV to country geometries using `topojson`. A square-root size scale, implemented with `d3.scaleSqrt`, drives the circle radii, and a legend is built through custom `sizeLegend` and `colorLegend` functions.

Circles on a Map

This visualization uses a natural Earth projection map to display the population of each country for 2018, with the area of each circle proportional to its population. The map supports pan, zoom, and hover interactions for additional details. The code employs d3.geoPath and d3.geoNaturalEarth1 for the map projection, along with d3.scaleSqrt for sizing the circles. Population data comes from a CSV file, while country boundaries are sourced from TopoJSON. Legends for both color and size are rendered using SVG, with hover effects revealing population figures.

Circles on a Map

This visualization maps global population data by country, using circle area to represent population size for 2018. Users can pan and zoom across a natural Earth projection, and hover to reveal exact population counts. The visualization uses d3.geoPath, d3.geoNaturalEarth1, d3.scaleSqrt, and d3.zoom, with data from a CSV joined to TopoJSON world atlas geometry. A size legend and color legend are rendered as SVG, with circles and country borders styled for clarity.

Circles on a map

This visualization displays a natural Earth projection map with circles overlaid on each country, sized proportionally to its 2018 population and colored by data availability. The map uses d3.geoNaturalEarth1 and d3.geoPath for geographic rendering, while d3.scaleSqrt and d3.geoCentroid position the circles. Population data is loaded from a UN CSV file, merged with TopoJSON world geometry via topojson.feature, and filtered for valid values. Zooming is enabled through d3.zoom, and a size legend with formatted tick labels explains the circle scale. Countries missing data appear in red, and hover tooltips display the region and exact population.

Circles on a Map

This visualization uses a natural Earth projection to display country boundaries and population data. Circles sized with `d3.scaleSqrt` are positioned at each country's centroid using `d3.geoCentroid`, with circle area proportional to 2018 population estimates from the UN. Users can pan and zoom via `d3.zoom`, while hovering reveals a tooltip with country name and population. The code employs `d3.geoPath`, `topojson.feature`, and a custom size legend rendered in SVG.

Circles on a Map

This visualization displays global population by country using circles overlaid on a natural Earth projection map, with circle area proportional to 2018 population data. Users can pan and zoom the map and hover over countries to see region names and population figures. The implementation uses D3 v5 with `geoNaturalEarth1`, `geoPath`, `geoCentroid`, and `scaleSqrt` for sizing, while loading data from a CSV file and TopoJSON world atlas. Circle positions derive from projected centroids, and a custom size legend communicates the population scale.

Circles on a Map

This visualization displays the world’s population by country, with circle area scaled to each nation’s 2018 population, mapped onto a natural Earth projection using d3.geoNaturalEarth1 and d3.geoPath. A square-root scale (d3.scaleSqrt) determines circle radii, while a separate size legend communicates the mapping. Users can pan and zoom via d3.zoom, and hover over countries to reveal a tooltip with the region and population count. The code uses D3 v5, TopoJSON for world geometry, and CSV data from the United Nations, with an SVG rendering approach.
