A reusable D3 scatter plot visualizes COVID-19 death averages in the United States over time, using data from the NY Times rolling-averages dataset. The chart renders an SVG with time-scaled x-axis and linear-scaled y-axis, plotting daily death averages as small circles. Labels annotate the national trend, noting the vaccination milestone at 30% and citing the NYT source. The implementation uses D3 v6 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `timeFormat`, with a configurable chart factory pattern for reusable accessor properties.
