This visualization shows how the average electric vehicle range changes by model year, using a line chart that aggregates data points through D3’s `d3.rollups` and `d3.mean` functions. The chart loads CSV data via `d3.csv`, then applies `d3.scaleLinear` for both axes and generates a smooth monotone curve with `d3.line` and `d3.curveMonotoneX`. The SVG rendering includes labeled axes, a title, and a blue stroke path, all styled through D3 v7’s selection and axis APIs.
