This scatter plot displays one week of San Francisco temperatures, with each point representing a temperature reading over time. The chart uses D3.js version 5 with an SVG rendering, featuring axes with tick marks and labels for time and temperature. The visualization includes interactive tooltips that appear on mouseover, showing a population value. Data is loaded from a CSV file, parsed with timestamps converted to Date objects and temperatures to numbers. The code uses `scaleTime`, `scaleLinear`, `axisLeft`, and `axisBottom` from D3 to construct the coordinate system and axes.
