This scatter plot visualizes temperature readings in San Francisco over a week, with time on the x-axis and temperature on the y-axis. Blue circles mark each data point, and the chart includes labeled axes and a title. The visualization is built with D3 v5, using `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to render an SVG. Data is loaded from a CSV file hosted on VizHub, with timestamps parsed as JavaScript `Date` objects and temperatures converted to numbers before plotting.
