This scatterplot displays the temperature of San Francisco over time, with each circle representing a measurement. The visualization uses D3 v7 to load CSV data and render an SVG. It employs `scaleTime` and `scaleLinear` to map timestamps and temperature values to pixel coordinates, with `axisBottom` and `axisLeft` generating labeled axes and gridlines. The circles are styled with a semi-transparent steelblue fill, and the chart includes titles for both axes and the overall graph.
