A scatter plot tracks COVID-19 confirmed cases against deaths on logarithmic axes, with each point representing a country and its population and regional color encoding. Overlaid dark-red lines radiate from the origin, annotating fatality rates and country labels. A circular legend explains the point size, color, and opacity encoding. The React-based D3 visualization uses `d3.axisBottom`, `d3.min`, and `d3.ticks` for axes and grid, while custom functions render the legend, annotations, and rotated fatality labels, using county-level GeoJSON data from `county.json` as a backdrop.
