This scatter plot visualizes COVID-19 deaths in the US over time using rolling averages from the NY Times dataset. The chart displays dates on the x-axis and average deaths on the y-axis, with each point representing a daily observation. The visualization is built as a reusable D3 framework using the `scatterPlot` function, which leverages `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` from D3 6.7.0. The plot includes an annotated line marking when vaccination reached 30%, and is rendered as an SVG with custom styling.
