This scatter plot visualizes a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. Circles represent individual data points, plotted using `d3.scaleTime` and `d3.scaleLinear`, with axes generated by `d3.axisBottom` and `d3.axisLeft`. The data is loaded from a CSV file via `d3.csv` and rendered as SVG. The chart includes labeled axes, a title, and grid lines created by tick sizes.
