Forked from Circles on a Map

This visualization displays global population data for 2018 using proportional circles positioned over a natural Earth projection map. The area of each circle corresponds to a country’s population, and hovering over a country reveals its name and population count, while missing data appears in red. Pan and zoom interactions are enabled via d3.zoom. The map is rendered using SVG with d3.geoPath and topojson for world geometries, while population data is loaded from a CSV file. A size legend built with d3.scaleSqrt explains the circle scaling, and d3.schemeSpectral is used for the color legend.

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.

Fork of Circles on a Map

This visualization displays global population data as proportional circles positioned on a world map. Each circle's area corresponds to a country's 2018 population, with hover tooltips revealing specific values. The map supports pan and zoom interactions. Built with D3 v5, it uses `geoNaturalEarth1` for the projection, `geoPath` for rendering country boundaries, and `scaleSqrt` for circle sizing. Population data comes from a CSV dataset merged with TopoJSON world atlas geometries. A size legend and color legend are generated using custom D3 modules.

Fork of Circles on a Map

This visualization shows global population for 2018 using circles on a natural Earth projection map, with circle area proportional to population and hover tooltips revealing country names and values. Users can pan and zoom the map. The code uses d3.geoNaturalEarth1, d3.geoPath, d3.geoCentroid, and d3.zoom, with population data from a CSV processed via d3.csv and country geometries from TopoJSON. A square-root size scale and a custom size legend with tick labels display the quantitative mapping.

Fork of Circles on a Map

This visualization displays global population data for 2018 using proportional circles positioned at country centroids on a natural Earth projection. A square-root scale encodes population values as circle areas, with a color legend indicating missing data. Users can pan and zoom the map, and hover over countries for detailed population figures sourced from UN data. The implementation uses d3.geoPath for map rendering, d3.scaleSqrt for sizing, and d3.zoom for interactive navigation.

Fork of Circles on a Map

This visualization displays world population by country using proportional circles on a natural Earth projection map. The area of each circle corresponds to the country’s 2018 population, with data sourced from a UN CSV and a 50m world atlas TopoJSON. The visualization supports pan and zoom interactions, and hovering over a country reveals its name and population. The code uses d3.geoPath for map rendering, d3.scaleSqrt for circle sizing, and custom sizeLegend and colorLegend components to create legends, with SVG as the rendering format.

Fork of Circles on a Map

This visualization displays global population by country using proportional circles overlaid on a natural Earth projection map. Circle area corresponds to each country’s 2018 population, with missing data marked in red. Users can pan and zoom via d3.zoom, while hovering reveals country names and population counts. Built with D3 v5, it uses d3.geoPath, d3.geoCentroid, and d3.scaleSqrt to position and size circles, sourced from a CSV of UN population data and TopoJSON world boundaries.

Fork of Circles on a Map

This visualization shows global population by country using scaled circles on a natural Earth projection map. Circle area corresponds to 2018 population data, while pan and zoom interactions allow exploration, and hovering reveals country names and population figures via tooltips. The implementation uses d3.geoPath for map rendering, d3.scaleSqrt for circle sizing, d3.zoom for navigation, and TopoJSON for world geography. A color legend and size legend explain the encoding, with data loaded from a CSV file merged with the TopoJSON world atlas.

Fork of Circles on a Map

This visualization uses proportional circles on a natural Earth projection map to show population by country for 2018, with circle area scaled via d3.scaleSqrt and hover tooltips revealing exact figures. It integrates d3.zoom for panning and zooming, d3.geoPath for rendering country boundaries from TopoJSON, and d3.geoCentroid to position circles at country centers. A color legend and size legend annotate the view, while data is loaded via d3.csv and d3.json. Missing population data renders countries in light red, and hover highlights countries in teal.
