This area chart shows the number of Supreme Court cases decided per term from 2018 to 2024, with a red filled area beneath a black line and individual data points. The data is loaded from a CSV file and aggregated using D3’s `rollups` function. The visualization uses D3 scales (`scaleLinear`), axes (`axisBottom`, `axisLeft`), and an area generator (`area`) to render the chart, with labels added via the `@curran/axis-labels` library.
