This example displays a natural Earth projection world map where each country is filled with a light gray or pink color based on whether population data exists for 2020. Circles sized by population are placed at each country’s centroid using `geoCentroid` and scaled with `scaleSqrt`. The visualization uses `d3.geoPath` to render the map, `d3.zoom` for panning and zooming, and includes size and color legends built from reusable components. Data comes from UN population CSV files and TopoJSON world atlas geometry, processed with `topojson.feature`.

Circles on a Map

This example displays a natural Earth projection world map with semi-transparent teal circles sized by each country’s 2018 population estimate, using d3.geoNaturalEarth1, d3.geoPath, and d3.geoCentroid to position circles at country centers. A d3.scaleSqrt maps population values to circle radii, and a custom size legend shows graduated tick marks. Countries missing data appear pink, and hovering highlights them turquoise. The visualization loads UN population CSV data and TopoJSON world geometry via d3.csv and d3.json, renders SVG paths and circles, and supports zooming through d3.zoom.

Circles on a Map

This example displays a natural Earth projection map with semi-transparent teal circles sized by each country’s 2018 population, drawn from UN population estimates and world atlas TopoJSON data. A square-root size scale encodes population values, with a corresponding size legend and an ordinal color legend for missing data. The visualization uses d3.geoPath and d3.geoNaturalEarth1 for map geometry, d3.geoCentroid to position circles, and d3.zoom for panning and zooming. Hovering a country reveals a tooltip with its region and formatted population.

Circles on a map

This example displays a natural Earth projection world map with semi-transparent teal circles overlaid on each country, sized by 2018 population data from the UN. Country boundaries are drawn using `d3.geoPath` and TopoJSON, while missing population values appear as pink regions. A `d3.scaleSqrt` maps population to circle radius, and a custom legend shows the scale. The map supports pan and zoom via `d3.zoom`, with circle positioning computed from `d3.geoCentroid` and projected coordinates.

Circles on a map

This example uses a natural Earth projection to render a world map with circles sized by 2018 population estimates. The visualization displays countries in two colors, distinguishing those with population data from those without. It uses d3.geoNaturalEarth1, d3.geoPath, and d3.geoCentroid to project country boundaries and position circles at country centroids. A d3.scaleSqrt maps population values to circle radii, with a custom size legend and zoom interaction via d3.zoom. Population data comes from a CSV file merged with TopoJSON world atlas geometry.

Circles on Map

This example displays a world map with circles positioned at the centroids of countries, sized to reflect their 2018 population estimates. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and renders geographic boundaries with `d3.geoPath`, while circle radii are scaled with `d3.scaleSqrt`. Populated countries appear with teal circles, and gray or pink fills indicate data availability. The visualization loads population data from a CSV and country geometries from TopoJSON, and supports zooming through `d3.zoom`. Hovering reveals a tooltip with the region name and population count.

Circles on a map

This example displays a natural Earth projection world map with semi-transparent teal circles overlaid on each country, sized according to estimated 2018 population data from the UN. The map uses `d3.geoPath` and `d3.geoNaturalEarth1` to render country outlines from TopoJSON, while `d3.scaleSqrt` maps population values to circle radii. A legend with `d3.scaleSqrt` ticks and a color legend for missing data accompany the visualization, which supports zooming via `d3.zoom`.

Circles on a Map

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.

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`.
