This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. It shows temperature trends over time using a smooth area path, with axes labeled “Time” and “Temperature.” The visualization is built with D3 v5, using `d3.csv` to load data, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft` for scales and axes. A filled area is generated with `d3.area` and `d3.curveBasis`, rendered as SVG.
