This stylized line chart visualizes weekly temperature trends in San Francisco using data loaded from a CSV file via `d3.csv`. The chart renders as an SVG with a smooth curve generated by `d3.line().curve(d3.curveNatural)`, overlaid with axis ticks and labels created through custom React components. The visualization leverages `d3.scaleTime` and `d3.scaleLinear` for positioning, while `d3.extent` and `d3.timeFormat` handle domain calculation and tick formatting. Circles on the curve include native SVG `<title>` tooltips, and the design employs a Poppins font and teal color scheme.
