This scatter plot displays temperature readings throughout a week in San Francisco, with time on the x-axis and temperature on the y-axis. Purple, semi-transparent circles reveal each data point. The visualization uses d3.scaleTime and d3.scaleLinear to map data values to SVG coordinates, with d3.axisBottom and d3.axisLeft generating the labeled axes. Data is loaded asynchronously from a CSV file using d3.csv, and the axes include custom tick sizing and grid lines.
