This fork of a line chart displays temperature readings for San Francisco over time, using an area path rendered by `d3.area` with a `curveBasis` to smooth the line. The visualization employs `d3.scaleTime` for the x-axis and `d3.scaleLinear` for the y-axis, with axes generated by `d3.axisBottom` and `d3.axisLeft`. Data loads from a CSV file via `d3.csv`, parsing timestamps and numeric temperatures. The chart includes labeled axes, a title, and grid lines styled with CSS within an SVG canvas.
