This scatter plot displays temperature readings over time in San Francisco, with each orange point representing a measurement and a purple basis curve connecting them. The visualization uses D3 v5's `scaleTime` and `scaleLinear` for the axes, while `axisBottom` and `axisLeft` render gridlines and tick labels. Data is loaded as CSV and rendered as SVG, with circles and a smoothed path drawn using `line` and `curveBasis`.
