This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City, with time on the x-axis and temperature in degrees Celsius on the y-axis. The visualization uses d3.v5 to load CSV data via `d3.csv`, scales with `scaleTime` and `scaleLinear`, and renders axes through `axisBottom` and `axisLeft`. A smooth curve is drawn using the `line` generator with `curveBasis`, and the SVG output includes labeled axes and a title.
