This scatterplot visualizes temperature readings in San Francisco over time, with each red circle representing a measurement plotted against a temporal x-axis and a linear temperature y-axis. The visualization uses D3’s scaleTime and scaleLinear to map data coordinates, while axisBottom and axisLeft generate the labeled axes with grid lines. The chart reads data from a CSV file hosted on GitHub, parses timestamps and numeric temperatures, and renders the result as SVG circles within a styled layout featuring a title and axis labels.
