This area chart visualizes the Highway MPG for different car makes, using a dataset loaded from a CSV file hosted on GitHub. Built with D3.js v7 and rendered as an SVG, the chart employs `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.area` to generate the filled area path. The x-axis labels are rotated for readability, and axes are created using `d3.axisBottom` and `d3.axisLeft`.
