This line chart visualizes temperature readings over time, using a smooth natural curve to connect data points from a CSV dataset of weekly San Francisco temperatures. The chart displays time on the x-axis using `d3.scaleTime` with weekday tick labels formatted via `timeFormat`, while temperature values are plotted on a linear y-axis. Built with React and rendered as SVG, the visualization leverages d3 v6 functions including `extent`, `line`, and `curveNatural` for the path generation, with axes constructed through reusable React components.
