This area chart shows a week of temperature readings in San Francisco, with time on the x-axis and degrees Celsius on the y-axis. The data comes from the Data Canvas - Sense Your City project. Built with D3 v6, it uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and an `area` generator with `curveBasis` to render the smooth maroon filled path. CSV loading via `d3.csv` and a styled SVG render the chart.
