A stylized line chart displays temperature over time for San Francisco, using a smooth natural curve to connect data points against custom axes. Built with React and D3 v5, the visualization employs `scaleTime`, `scaleLinear`, and `line().curve(curveNatural)` to generate an SVG path. The data loads from a remote CSV, filtered to a single city, with weekday tick labels formatted via `timeFormat`. Custom axis components render gridlines and labels, while the Zen Loop font and teal color scheme give the chart a distinct, hand-drawn aesthetic.
