This visualization presents a hierarchical tree map of COVID-19 case data, showing confirmed cases, deaths, and recoveries by continent and country. The root node aggregates global totals, branching into regions like Asia and individual nations, with China expanding into its provinces. Built with D3.js v5, the code uses a standard tree layout to position nodes and likely links, with each node displaying its name and associated metrics. The static data is embedded directly in the script, sourced from real-world pandemic statistics as of late April 2020. The visualization uses a simple, unstyled SVG rendering without interactive features or transitions.
