This visualization plots temperature over time as a smooth line chart using React and D3 v5. The temperature data is loaded from a CSV file via `d3.csv` and rendered with SVG paths using D3’s `line` and `curveNatural` generators. Axes are built with `scaleLinear` for both dimensions, with custom React components for the bottom and left ticks. The chart includes labeled axes for "Time" and "Temperature," and while circle marks are defined in the code, they are currently commented out, so only the dark grey curved line is displayed. The styling applies custom fonts and bold axis labels via an external stylesheet.
