This line chart displays daily temperature readings over a week in San Francisco, using a smooth natural curve to connect data points. The React application loads the dataset via `d3.csv` and renders an SVG visualization with `d3.scaleTime` for the x-axis and `d3.scaleLinear` for the y-axis. Custom `AxisBottom` and `AxisLeft` components generate tick marks, while the `Marks` component draws the path using `d3.line` with `curveNatural`. The chart includes labeled axes for Timestamp and Temperature, with loading state feedback.
