A world map visualizes population by country via teal circles, with circle area scaled to 2018 population data. Pan and zoom are enabled through the `d3.zoom` behavior. Hovering a country reveals details, while a custom size legend displays the population scale. The visualization uses the `d3.geoNaturalEarth1` projection, `d3.geoPath` for rendering country borders, and `d3.scaleSqrt` for circle sizing. Data merges UN CSV statistics with world atlas TopoJSON, rendered as SVG with CSS styling for hover effects.

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 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 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 visualizes population by country using scaled circles overlaid on a natural Earth projection map, with circle area proportional to each country’s 2018 population. Pan and zoom are enabled via d3.zoom, and hovering over a country reveals its exact population through a title tooltip. The map is rendered as SVG using d3.geoPath and topojson, while a d3.scaleSqrt maps population values to circle radii. A size legend generated with custom d3 code displays population ticks, and the data is loaded from a CSV and a TopoJSON world atlas file.

Circles on a Map

This example visualizes global population data on an interactive world map, with circular markers sized proportionally to each country’s 2018 population via a square-root scale. Hovering over a country reveals its exact population in a tooltip. The map uses d3.geoNaturalEarth1 and d3.geoPath for geographic projection and rendering, while d3.zoom enables pan and zoom. Circles are positioned using d3.geoCentroid, and data merges CSV population figures with TopoJSON world boundaries using topojson.feature, with legends built through custom colorLegend and sizeLegend modules.

Circles on a Map

This visualization maps population by country using circles positioned at each country’s centroid, with circle area proportional to 2018 population data loaded from a CSV and joined to TopoJSON world geometry via d3.csv and topojson.feature. d3.geoNaturalEarth1, d3.geoPath, and d3.geoCentroid project the map, while d3.scaleSqrt sizes the circles. The map supports pan and zoom through d3.zoom, and hovering reveals country names and population values via SVG title elements. A custom size legend and a separate color legend are rendered as SVG groups.

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 example visualizes population by country using circles on a world map, with circle area proportional to 2018 population data. Users can pan and zoom the map, and hover over countries to see detailed figures. The visualization uses d3.geoNaturalEarth1 projection with d3.geoPath for map outlines, d3.scaleSqrt for circle sizing, and a custom size legend. Population data is loaded from a CSV file, while country boundaries come from TopoJSON, and map interactions are enabled through d3.zoom.

Circles on a Map

This map visualization depicts world population by country, with circle area scaled to the 2020 population figures. Users can pan and zoom across the interactive SVG, and hovering over a country highlights it while revealing a tooltip with the region name and population. The visualization is built with d3.v5, using geoNaturalEarth1, geoPath, and geoCentroid for the map projection, while loadAndProcessData merges CSV population data with TopoJSON world atlas shapes. A square-root scale controls circle size, and custom legends render the data encoding.
