This visualization displays temperature over time as a smooth, filled area chart. The chart uses a time-based x-axis and a linear y-axis, with an overlaid line and semi-transparent pink fill. Built with D3 v5, it loads CSV data from a remote source and renders via SVG. The code specifically utilizes `scaleTime`, `scaleLinear`, `area`, `curveBasis`, `axisLeft`, and `axisBottom` to construct the plot, with custom styling applied through CSS.
