Temperature in San Francisco Line Chart
This line chart displays a week of temperature data in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis, using a smoothed curve to connect the data points. The visualization is built with D3 v5, using `scaleTime` and `scaleLinear` for the axes, `line` with `curveBasis` for the path, and `axisBottom` and `axisLeft` for tick rendering. The data originates from the Data Canvas - Sense Your City project and is loaded as a CSV from an external URL.
