This visualization displays temperature trends in the Netherlands over a week, with two overlaid line charts showing actual and perceived temperatures across time. The line paths use smooth curve interpolation through d3’s `line` with `curveNatural`, while the axes employ custom React components. The chart is rendered as an SVG using React, with scales set by `d3.scaleTime` for the x-axis and `d3.scaleLinear` for temperature ranges. Data is preprocessed from hourly weather records, extracting time, actual Celsius temperature, and feels-like values for each point.
