This visualization displays COVID-19 daily death averages across the United States as a scatter plot, with time on the x-axis and deaths on the y-axis. It uses a reusable D3 chart framework with `scaleTime`, `scaleLinear`, and `axisBottom` to render the timeline, while the data comes from the NY Times rolling averages CSV. The SVG rendering includes custom axis labels, a title, and source attribution, with a circular marker for each date point. The code demonstrates the reusable chart pattern with getter/setter accessors for width, height, data, and margin.
