Forked from Choropleth Map

This visualization presents a world map showing cumulative COVID-19 cases as of June 6, 2021, using a natural Earth projection rendered with SVG via `d3.geoPath`. Circle markers sized by a square-root scale represent case counts per country, while a corresponding size legend and a color legend for missing data are included. The map supports zooming through `d3.zoom`, and tooltips display country names and case totals using `d3.format`. Data is loaded from a CSV file merged with TopoJSON world geometry via `topojson.feature`, with graticule lines and hover effects on country paths.

Fork of Covid19 world map

This map visualizes cumulative COVID-19 cases per country as of June 6, 2021, using circle size to encode case counts over a natural Earth projection. Missing data appears in red, while countries with data are gray. The visualization loads spatial boundaries from TopoJSON and joins them with case counts from a CSV using `d3.csv` and `d3.json`. It employs `d3.geoPath` for map rendering, `d3.geoNaturalEarth1` for projection, and `d3.scaleSqrt` for proportional symbol sizing, with zoom via `d3.zoom` and interactive tooltips.

Covid-19 cases global data

This visualization displays global COVID-19 case data on an interactive world map using a natural Earth projection, with each country rendered as a green SVG path that turns red on hover. The map uses d3.geoPath with d3.geoNaturalEarth1 for geographic projection, and d3.zoom enables panning and zooming. Country boundaries come from the world-atlas TopoJSON dataset, while country names are joined via the corresponding TSV file. The sphere background is styled blue, and the visualization relies on D3 v5 and topojson.feature to process the geographic data.

Covid-19

A world map shows the geographic spread and cumulative confirmed COVID-19 cases as of March 25, 2020. Orange circles, sized with a square-root scale, are positioned by country coordinates using a Mercator projection and the `geoPath` and `geoMercator` functions from D3 v5. The data is loaded from a CSV file and rendered as SVG, with the world map built from TopoJSON data and the slider element in the HTML interface.

Covid-19

The visualization maps COVID-19 case counts per country on a world map using SVG circles, with circle radius scaled proportionally to the number of cases on March 25, 2020. It displays data from the Humanitarian Data Exchange, sourced from a CSV file containing daily case numbers since January 22, 2020. The map uses D3 v5’s `geoMercator` projection, `geoPath` to draw country boundaries, and `scaleSqrt` for radius scaling. A range slider is present, though the displayed date label shows placeholder text.

Covid-19

This visualization shows the global spread of COVID-19 by plotting circular markers on a world map, with each circle sized proportionally to the total reported cases for a country on March 25, 2020. The map uses a geoMercator projection with d3.geoPath to render country boundaries from TopoJSON. COVID-19 data from a CSV file is loaded with d3.csv, and circle radii are scaled using d3.scaleSqrt. An interactive range slider is present, though its current implementation only displays static text.

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.

Covid-19 global cases

This choropleth map visualizes global COVID-19 cases by country, using a color scale based on economic grouping. The map renders with D3’s `geoNaturalEarth1` projection and `geoPath`, allowing zoom interactions via `d3.zoom`. A clickable ordinal color legend filters highlighted countries, with dimming for non-selected regions. Data is loaded from a CSV and TopoJSON using `d3.csv` and `d3.json`. The visualization uses SVG elements and applies hover effects through CSS.

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.
