This line chart visualizes one week of temperature data in San Francisco, sourced from the Data Canvas - Sense Your City dataset. It displays temperature in degrees Celsius over time, using a smoothed line curve to show trends. The visualization is built with D3 v5, using `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis`. Data is loaded via `csv` and rendered as an SVG, with gridlines, axis labels, and a title.
