Animated circles on a natural Earth projection map visualize COVID-19 confirmed cases and deaths over time, with circle area encoding magnitude. Data is drawn from a temporal CSV and merged with country geometries loaded via TopoJSON. Hovering reveals population figures. Users can pan and zoom, while a color legend distinguishes levels. The visualization uses D3 v5 APIs including `geoPath`, `geoNaturalEarth1`, `scaleSqrt`, `zoom`, and transitions.

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

Circles on a Map visualizes COVID-19 confirmed cases by country as proportional circles overlaid on a natural Earth projection. Circle area encodes case counts via a square-root scale, and hovering highlights country boundaries with a tooltip showing the country name and case total. The visualization supports pan and zoom interactions. Built with D3 v5, it uses `d3.geoPath` with TopoJSON world data, `d3.geoCentroid` for circle placement, and a zoom behavior applied to an SVG group. Population data from the UN and case data from a CSV drive the marks.

Circles on a Map

This visualization presents daily COVID-19 case data as an animated, zoomable map. Teal circles sized by confirmed cases and red circles for deaths appear over each country, with a date ticker and hover tooltips providing detail. Built with D3.js (v5), it uses `geoPath` and a Natural Earth projection, animating circle radii via `transition()`. Population data comes from a CSV file (`data01.csv`) and country shapes from the VisionsCarto World Atlas TopoJSON.

Circles on a map

This example visualizes confirmed COVID-19 cases as of August 30, 2020, using scaled circles positioned at country centroids on a natural Earth projection. It renders an SVG world map with d3.geoPath, applies a d3.scaleSqrt for circle radii, and includes interactive pan/zoom via d3.zoom. A color legend uses d3.scaleOrdinal with schemeSpectral, while a separate size legend displays tick marks. Data comes from a CSV time series and TopoJSON world atlas, processed with topojson.feature, with hover tooltips showing country names and case counts.

Circles on a map

This example visualizes COVID-19 case counts by country on a natural Earth projection map, with circles sized by total cases as of May 16, 2020. Using d3.geoNaturalEarth1 and d3.geoPath, it renders country outlines and positions proportional circles via d3.geoCentroid. A d3.scaleSqrt maps case numbers to circle radii, and a custom size legend (with d3.format) explains the scaling. The map supports zooming through d3.zoom, while country data is joined from a CSV file and TopoJSON world-atlas geometry.

Circles on a map

This example visualizes the global spread of COVID-19 cases on a date in August 2020, plotting semi-transparent red circles on a natural Earth projection map. Circle size encodes case counts using a square-root scale, while hover tooltips show country names and totals. Built with React and D3 v5, it uses `d3.geoNaturalEarth1`, `d3.geoPath`, `d3.geoCentroid`, and `d3.zoom` for navigation, with TopoJSON world data and CSV time-series data from a COVID-19 repository. Custom legends display color and size scales via `d3.scaleOrdinal` and `d3.scaleSqrt`.

Circles on a map

This visualization displays confirmed COVID-19 cases per country on a world map, using a natural Earth projection from the topojson library. The map shows circles sized by the square root of case numbers, with a legend explaining the scaling. It uses d3.select, d3.geoPath, and d3.scaleSqrt for rendering, and supports interactive zooming. Data is loaded from a CSV file, and the map is rendered as SVG with hover tooltips showing country names and case counts.

Circles on a map

This example visualizes the global spread of COVID-19 in early 2020 using a natural Earth projection map. Circles overlaid on each country represent population size, with a legend showing the scale. The visualization also plots the spread of the virus from country to country based on CSV data of transmission events. The code uses D3 v5 with `geoNaturalEarth1`, `geoPath`, `geoCentroid`, and `scaleSqrt` for the population-scaled circles. It loads TopoJSON for country boundaries, merges CSV data for coordinates, and supports zooming via `d3.zoom`.

Circles on a Map

This visualization displays the global distribution of new COVID-19 cases using proportional circles positioned by country centroids on a natural Earth projection. The circle areas encode population data loaded from CSV files, while tooltips reveal exact values on hover. Built with D3 v5, the visualization uses d3.geoPath for map rendering, d3.geoCentroid for positioning, d3.scaleSqrt for circle sizing, and d3.zoom for pan and zoom interactions. A size legend with d3.ticks communicates the scale, and world atlas TopoJSON provides the country boundaries.
