This scatter plot displays one week of temperature data in San Francisco, with time on the x-axis and degrees Celsius on the y-axis, sourced from the Data Canvas - Sense Your City project. Each circle represents a temperature reading, rendered as an SVG using D3 v5. The code employs `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.extent` for domain calculation, and `d3.axisBottom` and `d3.axisLeft` for tick marks, with gridlines and labeled axes.
