This area chart displays temperature measurements in San Francisco over time, using a filled orange region beneath a smooth curve to emphasize variation across the timeline. The visualization loads data from a CSV file, parses timestamps and numeric temperatures, and renders an SVG with D3.js v5. It uses `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and the `d3.area` generator with `curveBasis`. A title and labels for time and temperature axes are included, with gridlines and rotated axis text styled via CSS.
