This visualization uses D3.js to plot COVID-19 data from a WHO global dataset, showing total cases against total deaths for each country as individual circles. The scatter plot uses D3's `csv` loader and `scaleLinear` functions to map the data, with axes labeled "Total Cases" and "Total Deaths." Circles are rendered in steelblue, and the chart is drawn as an SVG in a React application. The code defines its own width, height, and margins, using D3's `axisBottom` and `axisLeft` to generate the axes.
