This scatter plot visualizes temperature readings collected hourly over a week in San Francisco. Each red circle represents a single timestamp and its corresponding temperature, with time plotted along the x-axis and temperature along the y-axis. The visualization uses D3 v5 scales, including `scaleTime` and `scaleLinear`, to map data values to SVG coordinates, and `axisBottom` and `axisLeft` for the labeled axes. The data is loaded from a CSV file using `d3.csv`.
