The chart shows global cumulative coronavirus deaths over time, with a simple line rising steeply as the outbreak progresses. Total daily counts are calculated by summing all reported deaths per date from the Johns Hopkins CSSE dataset. The visualization uses D3 v5 axis utilities, `d3.axisBottom` and `d3.axisLeft`, to render grid lines and date/death labels, while the line itself is generated with `d3.line`. The React component structure handles SVG rendering and margins.
