This area chart displays one week of temperature data in San Francisco, with time on the x-axis and degrees Celsius on the y-axis. The visualization uses an SVG-based area path filled with maroon, rendered via D3 v5’s `area`, `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` APIs. The data is loaded from a CSV file and processed to convert timestamps and temperatures. Axes include labeled ticks and gridlines, with a smooth curve applied through `curveBasis`.
