This scatter plot visualizes a week of temperature readings in San Francisco, plotting time on the x-axis against temperature in Celsius on the y-axis. Each data point is rendered as a semi-transparent SteelBlue circle, with the title “A Week in San Francisco” displayed above the chart. The visualization is built using D3 v5, employing `scaleTime` and `scaleLinear` for axes, `axisBottom` and `axisLeft` for tick marks, and SVG circles for data points. Data is loaded from a CSV file fetched via a Gist URL, with timestamps parsed as `Date` objects.
