This example shows a genre distribution from a CSV dataset as a single steelblue area chart, with genres on the x-axis and aggregated counts on the y-axis. The code uses D3 v7 with `d3.csv` to load remote data, `d3.rollup` to sum counts per genre, and `d3.area` with `d3.scaleBand` and `d3.scaleLinear` to generate the SVG path. It renders axes via `d3.axisBottom` and `d3.axisLeft`, and includes labeled axes and a title.
