Temperature in San Francisco Line Chart
This line chart displays one week of temperature data in San Francisco, sourced from the Data Canvas Sense Your City dataset. The visualization shows temperature trends over time on a smooth curve, with time on the x-axis and temperature on the y-axis. The chart uses D3 v5 and SVG rendering, employing `scaleTime` and `scaleLinear` for axes, `line` with `curveBasis` for the smoothed path, and `axisLeft` and `axisBottom` for gridlines and labels. The title "A Week in San Francisco" appears at the top.
