This scatter plot displays temperature readings over the course of a week in San Francisco, with time on the x-axis and temperature on the y-axis. The visualization uses d3.scaleTime and d3.scaleLinear to map the data, while d3.axisBottom and d3.axisLeft render the axes with gridlines. Data comes from a CSV file loaded via d3.csv, and each point is drawn as an SVG circle with a fixed radius. The chart includes labeled axes and a title, all rendered in SVG with d3’s selection and data-join methods.
