This line chart visualizes temperature readings over time, showing a continuous trend with individual data points marked as circles. The chart uses D3.js v5 within a React component, rendering SVG elements for precise control. Axes are generated with `scaleTime` and `scaleLinear`, while the line path is created using D3's `line()` with `curveNatural`. The data is loaded from a CSV file via D3's `csv` function.
