This area chart tracks electric vehicle sales in thousands over a sequence of years, using D3.js v7 with SVG rendering. The code loads a CSV dataset via `d3.csv`, sorts the data chronologically, and applies linear scales with `d3.scaleLinear` for both axes. It generates a filled area path using `d3.area` and overlays a stroked line with `d3.line`, plus data point circles. Axis labels and a bold title are included, with the chart drawn within a defined margin using the SVG coordinate system.
