This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City, with time on the x-axis and temperature in degrees Celsius on the y-axis. The chart uses D3 v5 with SVG rendering, employing `scaleTime` and `scaleLinear` to map the data, `axisBottom` and `axisLeft` for labeled axes, and a `line` generator with `curveBasis` to draw a smooth curve. The visualization includes gridlines, axis labels, and a title, with data parsed from a CSV file.
