This chart visualizes the cumulative count of COVID-19 deaths over time using a linear Y axis, making the growth in total deaths readily apparent against the date range. The data originates from the Johns Hopkins Coronavirus dataset, accessed as a CSV file. The React-based visualization employs D3 version 5 to build an SVG line chart, with `scaleTime` and `scaleLinear` mapping the data, `line` creating the path, and `axisBottom` and `axisLeft` rendering the axes.
