This line chart displays a week of temperature data in San Francisco, using a smooth curved line to connect daily measurements. The visualization, titled “A Week in San Francisco,” plots temperature in degrees Celsius over time. The code uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render the SVG. Data is loaded from a CSV file provided by Data Canvas - Sense Your City, with a styled maroon line, grid lines, and labeled axes.
