This area chart visualizes the total Spotify streams of the most streamed songs aggregated by their release year, showing how streaming totals trend across decades. The chart uses a steel-blue filled path generated by `d3.area()` with linear scales for both axes. Data is loaded from a remote CSV file using `d3.csv`, then processed with `d3.rollups` to sum streams per year before sorting chronologically. Axes are rendered using `d3.axisBottom` and `d3.axisLeft`, with the SVG output containing numbered year ticks and labeled axis titles.
