Forked from Circles on a Map

This visualization displays the population of each country in 2018 using circles overlaid on a natural Earth map, with circle area proportional to population via a square root scale. Users can pan and zoom the map and hover over countries to see exact population values. Built with D3 v5, it uses `d3.geoPath` and `geoNaturalEarth1` for map rendering, `d3.zoom` for interaction, and `d3.scaleSqrt` for the size legend. Population data is loaded from a CSV file and joined to TopoJSON country boundaries.

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 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 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 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 displays global population by country using scaled circles positioned at each country’s geographic centroid. Circle area corresponds to population magnitude, with a square-root scale controlling radius. The map supports pan and zoom, and hovering over a country reveals its name and population. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering country outlines from TopoJSON, and `d3.zoom` for interaction. Population data is loaded from a CSV file, and a custom size legend displays tick values using `d3.scaleSqrt`.

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 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 by country using scaled circles on a natural Earth projection map, with circle area proportional to each country's 2018 population. Users can pan and zoom via d3.zoom and hover over countries to see exact population figures through SVG title tooltips. The example uses d3.geoNaturalEarth1 and d3.geoPath for map rendering, d3.scaleSqrt for circle sizing, and topojson for world geometry. Population data is loaded from a CSV file, and countries lacking data appear in red rather than gray.

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.
