Forked from 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.

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 proportional circles overlaid on a natural Earth projection map. The area of each circle represents the population of its corresponding country, with circles positioned at the centroid of each nation. The map uses d3.geoPath for rendering country boundaries and a d3.scaleSqrt for sizing circles. Users can pan and zoom through the d3.zoom API, and hovering over a country reveals its population via a title tooltip. Data comes from a CSV joined with a TopoJSON world atlas, and a custom size legend communicates the circle-to-population mapping.

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 depicts global population data for 2018, using proportional circles on a natural Earth projection map. Country boundaries are rendered as SVG paths via `d3.geoPath`, while circle areas encode population using `d3.scaleSqrt`. Pan and zoom are enabled through a custom `zoom` event handler. Data is loaded from a CSV file and a TopoJSON world atlas, merged by country code. A size legend clarifies the scaling, and hovering on a country reveals its name and population via a tooltip.

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 global population data for 2018 using scaled circles positioned at country centroids on a natural Earth projection map. Circle area encodes population magnitude, while hovering reveals exact population figures and regional names. The map supports pan and zoom interactions through d3.zoom. Built with d3.geoNaturalEarth1 and d3.geoPath for map rendering, it uses d3.scaleSqrt for circle sizing and d3.scaleOrdinal with a spectral scheme for the categorical color legend. Population data comes from a CSV file processed alongside TopoJSON world boundaries.

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.
