This map visualizes global population estimates for 2018 using proportional circles overlaid on a geographic projection of the world. The visualization layers semi-transparent teal circles at each country’s centroid, with circle radius scaled by the square root of population via a legend. It employs D3’s `geoNaturalEarth1` projection, `geoPath`, and `geoCentroid` for map geometry, alongside `scaleSqrt` for sizing and `scaleOrdinal` for color. Data combines UN population CSV estimates with TopoJSON country boundaries, processed through local modules `loadAndProcessData` and `sizeLegend`.

AI-generated description

An example showing the capabilities of VizHub:

  • Loads D3 via UNPKG.
  • Demonstrates use of import from "d3".
  • Demonstrates use of import from local ES6 modules.

Circles on a Map

This map visualizes global population estimates for 2018 by projecting country centroids onto a natural Earth projection. Circles sized proportionally to population via a square-root scale are placed at each centroid, while uniform circles represent countries lacking data. The visualization uses D3.js APIs including `geoPath`, `geoCentroid`, `geoNaturalEarth1`, `scaleSqrt`, and `scaleOrdinal`, rendering with SVG. Population data comes from a CSV of UN estimates, and country shapes from a TopoJSON world atlas.

Circles on a Map

This visualization displays global population estimates for 2018 as proportional circles positioned at country centroids on a natural Earth projection map. Country boundaries are rendered as paths using d3.geoPath, while circle radii scale with population via d3.scaleSqrt. Two legends—a size legend and a color legend—communicate the quantitative mapping, with colors assigned through d3.scaleOrdinal. The map supports zooming through d3.zoom, and data comes from United Nations population estimates loaded as CSV and TopoJSON, processed with topojson.feature.

Circles on a Map

This visualization displays global population data for 2018 using proportional circles positioned at country centroids on a natural Earth projection. The map uses d3.geoPath and d3.geoCentroid to render countries and place scaled symbols, with d3.scaleSqrt determining circle radii. Hovering reveals country names and population values via SVG titles. Pan and zoom are enabled through d3.zoom, while a d3.scaleSqrt-based legend indicates population magnitudes. Data comes from a CSV file of UN population estimates joined with TopoJSON world geometry, rendered as SVG with color coding for missing values.

Circles on a Map

This visualization shows global population distribution using proportional circles on a natural Earth projection map. Circle size encodes each country’s 2018 population, with missing data shown in a distinct color. The map uses D3’s `geoNaturalEarth1` projection and `geoPath` to render borders. A `scaleSqrt` size legend and an ordinal color legend are included, and the interaction is a zoomable, event-driven map. Data comes from a UN CSV and a TopoJSON world atlas, processed via `topojson.feature`.

Circles on a Map

This interactive visualization displays global population estimates for 2018 as proportional circles centered on each country, overlaid on a natural Earth projection map. The map uses D3 v5’s `geoPath` and `geoNaturalEarth1`, while circle radii are scaled with `scaleSqrt` based on UN population data. A zoom behavior lets viewers pan and scale the map, and a custom size legend with tick labels explains the scaling. Countries without data appear in a distinct color, and hovering reveals country names and population figures via SVG `<title>` elements.

Circles on A Map

This visualization displays global population estimates for 2018 by drawing semi-transparent circles on a natural Earth projection map, with each circle positioned at a country's centroid and sized proportionally to its population. The map also includes a size legend and color legend for reference. Built with D3 v5, it uses `d3.geoNaturalEarth1` and `d3.geoPath` for map rendering, `d3.scaleSqrt` for circle sizing, and `d3.zoom` for interactivity. Population data comes from a UN dataset, with geographic boundaries from TopoJSON, and all elements are rendered as SVG.

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 maps global population by country using proportional circles centered on each nation’s geographic centroid. The area of each circle encodes the 2018 population estimate, with missing data shown in red on a gray map. Users can pan and zoom via d3.zoom, and hover over countries to reveal population values in tooltips. The code uses d3.geoPath, d3.geoNaturalEarth1, and topojson for map rendering, with a d3.scaleSqrt for circle sizing and a custom size legend.
