This interactive data visualization plots global COVID-19 confirmed cases as of May 4, 2020, using a geographic scatterplot. Each circle represents a province or country, positioned by longitude and latitude, with size and color encoding case counts via `d3.scaleSqrt` and `d3.scaleLinear`. Hovering a circle reveals a tooltip with country, coordinates, and case details. Built with D3 v7, the SVG chart reads CSV data from the CSSEGISandData GitHub repository and uses `d3.axisBottom` and `d3.axisLeft` for axes.
