This scatter plot visualizes one week of temperature data in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. Using D3 v5, the code employs `scaleTime` and `scaleLinear` for axis scaling, `axisBottom` and `axisLeft` for grid lines, and SVG circles to represent each temperature reading. The data is sourced from Data Canvas - Sense Your City, and the chart includes labeled axes and a title.
