This scatter plot shows one week of temperature in degrees Celsius in San Francisco, with time on the x-axis and temperature on the y-axis. Each circle represents a temperature reading, plotted using D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft`. The code loads the dataset from a CSV file via `csv()` and renders the SVG chart with margins, axis labels, and a title. Data originates from Data Canvas - Sense Your City, a public sensor project.
