This line chart displays one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. It plots time on the x-axis and temperature in degrees Celsius on the y-axis, using a smooth curved line to connect the data points. Built with D3 v5, the visualization uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render the SVG chart. The code also includes axis labels, a title, and a maroon line path styled via CSS.
