This stylized line chart visualizes temperature readings over a week in San Francisco, using a smooth natural curve to connect data points. The chart is built with React and rendered as SVG, with D3 v7 handling data loading via `d3.csv`, linear and time scaling through `scaleLinear` and `scaleTime`, and axis generation. Styling uses the Poppins font with teal-colored marks and custom tick formatting for weekday labels, while the underlying data comes from a CSV file containing timestamp and temperature values.
