This line chart displays one week of temperature data for San Francisco in degrees Celsius, using data from Data Canvas - Sense Your City. The visualization draws a smooth curve through the data points with a maroon stroke, while the axes include grid lines and labeled axes for time and temperature. The chart is rendered as an SVG using D3 v5, with scales created via `scaleTime` and `scaleLinear`, axes generated by `axisBottom` and `axisLeft`, and a line path shaped with `curveBasis`.
