This line chart displays one week of temperature readings in San Francisco, with time on the x-axis and degrees Celsius on the y-axis. The visualization uses D3 v5 to load CSV data from Data Canvas - Sense Your City, then applies `scaleTime` and `scaleLinear` for axes, `axisBottom` and `axisLeft` for ticks, and `line` with `curveBasis` for the smoothed path. SVG rendering includes labeled axes and a title.
