Fork of Fork of Scatter Plot COVID-19 Vaccination and Cases with Dual Axis
This scatter plot overlays COVID-19 vaccination rates (blue) and reported cases (gray) in the US over time, using dual y-axes to compare the two metrics. It reveals the inverse relationship between rising vaccination and falling case counts, with an annotation highlighting the percent reduction. The visualization uses D3 v6 APIs including `scaleTime`, `scaleLinear`, `axisLeft`, `axisRight`, and `selection.join` for animated circle transitions. Data comes from Our World in Data vaccine counts and NYT rolling averages, rendered as SVG elements with a menu to toggle between partial and full vaccination metrics.
