This line chart displays one week of temperature data in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. The visualization is rendered as an SVG using D3 v5, employing `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis` for smoothing. The chart includes labeled axes, a title, and grid lines created via tick marks. Data is loaded as CSV from the Data Canvas - Sense Your City dataset, with timestamps parsed as dates and temperatures converted to numbers.
