This visualization displays a week of temperature readings in San Francisco as an area chart, with time on the x-axis and temperature in degrees Celsius on the y-axis. The data comes from the UCI Machine Learning Repository’s Auto MPG dataset, loaded via `d3.csv`. The chart uses `d3.scaleTime` and `d3.scaleLinear` for axes, an `area` generator with `curveBasis` for the filled path, and `d3.axisLeft` and `d3.axisBottom` with gridlines. The SVG is rendered with a margin-based layout, including rotated axis labels and a title.
