This area chart visualizes one week of temperature data in San Francisco, with dates on the x-axis and temperatures in Celsius on the y-axis. The chart uses a smooth-curved area fill to emphasize temperature fluctuations over time. It is built with D3.js v5, using `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.area` with a `curveBasis` interpolation. The data originates from the Data Canvas - Sense Your City project, rendered as an SVG with styled gridlines and labels.
