This scatter plot visualizes one week of temperature readings in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. The circles are styled in steelblue, and the chart includes labeled axes and a title. Built with D3 v7, the code uses `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to render the SVG. It loads data from a CSV file hosted on VizHub, parsing timestamps and temperatures before joining the data to circles.
