This line chart tracks the cumulative number of deaths from a time series of COVID-19 data, sourced from the Johns Hopkins Coronavirus Dataset. The visualization uses a React front end with D3 v5 to render an SVG line path, with x- and y-axes drawn via `d3.axisBottom` and `d3.axisLeft`. The chart computes daily totals by summing the raw CSV values, with grid lines and axis labels styled through CSS.
