This area chart displays diesel values from 2005 to 2023. The visualization loads data from a CSV file via `d3.csv` and renders a violet filled area using the SVG `path` and the `d3.area` generator. It uses `d3.scaleLinear` for both axes, with formatted year ticks on the x-axis. The chart includes labeled axes and is built with D3 v7 within a plain HTML page.
