Temperature[line chart]
This line chart shows temperature readings over time in San Francisco, with time plotted on the x-axis and temperature on the y-axis using a smooth curve interpolation. The visualization is built with D3 v5 and rendered as SVG, using `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` for the path. Data is loaded via `d3.csv` from a GitHub Gist, and each timestamp is parsed as a JavaScript `Date` object before rendering.
