This area chart displays monthly sales figures, sourced from a CSV file, within a clean SVG layout. The visualization uses D3.js v6, employing `d3.csv` to load the data, `d3.scaleBand` for the categorical month axis, and `d3.scaleLinear` for the sales values. A filled path generated with `d3.area()` shows the trend, while `d3.axisBottom` and `d3.axisLeft` render the labeled axes. The chart highlights sales variation across the months, with a light teal fill for the area and a minimal, grid-free design.
