This scatter plot displays temperature readings over time in San Francisco, with each circle representing a data point plotted using linear scales for both axes. The SVG visualization uses d3.csv to load the dataset, d3.scaleLinear and extent to compute domains, and d3.axisBottom and axisLeft to render labeled axes with gridlines. Circles are styled with steelblue fill and partial opacity, while axis labels and a title are added as SVG text elements.
