This scatter plot visualizes a week of temperature readings in San Francisco, with time on the x-axis and degrees Celsius on the y-axis. The data is loaded via `d3.csv` from a dataset by Data Canvas - Sense Your City. Using D3 v5, the code employs `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to render an SVG with semi-transparent steelblue circles, axis labels, and a title, all styled through an external CSS file.
