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, using a smooth curve to connect the daily readings. The visualization loads CSV data and renders an SVG with D3 v5, employing `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis`. The chart includes labeled axes, grid lines, and a title, with styling defined in external CSS. The data originates from the Data Canvas - Sense Your City project.
