This fork of the ICE 7 Area Chart displays miles per gallon (mpg) for various car models using a line chart with a smooth basis curve. The SVG visualization uses D3 v5’s `scaleBand` and `scaleLinear` to map car models and mpg values, with axes labeled and styled via CSS. The line generator, `d3.line` with `curveBasis`, connects data points, while the dataset is loaded as CSV from a GitHub gist. The chart lacks a filled area, despite its title, focusing instead on the trend line.
