Forked from Circles on a Map

This visualization uses proportional circles to show each country’s population, with circle area scaled by the 2018 population data from a CSV file. The map renders with `d3.geoNaturalEarth1` projection and `d3.geoPath`, while a square-root scale (`d3.scaleSqrt`) determines circle radii. Users can pan and zoom via `d3.zoom`, and hovering a country reveals its name and population in a tooltip. A color legend and size legend are built with reusable D3 functions, and the map data comes from the visionscarto world atlas TopoJSON.

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 population by country using proportional circles on a natural Earth projection map, with circle area corresponding to each nation's 2018 population. Users can pan and zoom the map via d3.zoom and hover over countries to reveal population details in a tooltip. The code uses d3.geoPath, d3.geoCentroid, and d3.scaleSqrt to position and size circles, while a custom size legend and color legend are built with D3 selections. Population data originates from a CSV file, joined with TopoJSON world geometry using topojson.feature.

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 shows world population by country using scaled circles over 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 regional names and exact population figures. The code uses D3 v5 with `geoNaturalEarth1`, `geoPath`, `geoCentroid`, `scaleSqrt`, and `zoom`, rendering SVG paths for country borders and semi-transparent circles. Population data comes from a CSV file merged with TopoJSON world atlas geometry.

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 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 proportional circles centered on each country, with area encoding population size. The map supports pan and zoom, and hovering reveals a tooltip with the country name and exact population. It uses a natural Earth projection via d3.geoNaturalEarth1, with d3.geoPath for country boundaries and d3.scaleSqrt for circle sizing. A custom size legend and color legend (d3.scaleOrdinal with schemeSpectral) provide context. Data comes from a CSV file merged with world topology from TopoJSON, rendered as SVG. The implementation uses d3.zoom for interaction and d3.geoCentroid to position circles.

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.
