This area graph shows daily temperature variations in San Francisco over time, with the filled region rendered in maroon against a light grid. The visualization loads CSV data from a remote dataset, converts timestamps to JavaScript Date objects, and uses d3.scaleTime and d3.scaleLinear to map dates and temperatures to SVG coordinates. A d3.area generator creates the filled path, while d3.axisLeft and d3.axisBottom produce labeled axes with tick marks. The animation-capable SVG uses transitions that are included in the bundle but not explicitly triggered in this rendering.
