This scatter plot visualizes state-level COVID-19 trends by plotting death averages per 100,000 residents against case averages per 100,000, using New York Times rolling-averages data. Built with D3 v6, the reusable chart module `scatterPlot` uses `scaleLinear`, `axisLeft`, and `axisBottom` to render SVG circles and axes. The example demonstrates Mike Bostock’s reusable chart pattern, configuring width, height, margins, and radius through fluent setter methods.
