A scatter plot displays temperature readings in San Francisco throughout a day, with time on the x-axis and temperature on the y-axis. The chart uses d3.scaleTime and d3.scaleLinear to map the data, with axes rendered via d3.axisBottom and d3.axisLeft. Data loads from a CSV file using d3.csv, and circles are appended to an SVG element. The visualization includes labeled axes, a title, and gridlines created through tick marks, styled with orange circles and sans-serif text.
