A scatter plot displays temperature readings taken throughout a week in San Francisco, plotting each timestamp on the x-axis against its corresponding temperature on the y-axis. The visualization loads CSV data, converts timestamps to date objects, and uses d3.scaleTime and d3.scaleLinear to map data to SVG coordinates. d3.axisBottom and d3.axisLeft generate the axes with gridlines, while semi-transparent steelblue circles render each data point. The chart includes labeled axes and a title, with margins defining the plotting area.
