This area chart tracks website visits by month throughout 2023, with the data loaded from a CSV file via `d3.csv`. The visualization uses `d3.area()` with a band scale for months and a linear scale for visit counts, rendered as an SVG path. Axes are created with `d3.axisBottom` and `d3.axisLeft`, and both the chart area and axis labels are styled with steelblue fill and explicit text annotations.
