This area chart displays daily temperature readings over a one-week period in April 2024, with a steel-blue filled region beneath the line emphasizing the values. The visualization uses D3 v6 with an SVG rendering approach, employing `d3.area()` to generate the filled path, `d3.scaleTime()` for the date axis, and `d3.scaleLinear()` for the temperature axis. The chart includes rotated x-axis labels and axis titles for Date and Temperature (°C), with the area set to 50% opacity. Sample data is embedded directly in the script.
