This example visualizes COVID-19 cases, deaths, and population across countries using a bubble chart. Each bubble’s position maps total cases on the x-axis and total deaths on the y-axis, while bubble radius encodes population via a square-root scale. The chart is rendered in SVG using D3 v7, with linear scales, axis generators, and a legend showing population magnitude. Data is loaded asynchronously from a remote CSV file using `d3.csv`.

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.
