This scatter plot visualizes one week of hourly temperature readings in San Francisco, showing temperature trends over time. It uses a time-scaled x-axis and a linear y-axis to map temperature in degrees Celsius. The D3 v6 code leverages `scaleTime`, `scaleLinear`, `axisLeft`, and `axisBottom` to construct the chart. Each data point is rendered as a steelblue circle, with data sourced from the Data Canvas - Sense Your City initiative and parsed from a CSV file.
