This line chart displays temperature variations in San Francisco over a week, using a time-scaled x-axis and a temperature-scaled y-axis with axis labels and gridlines. The visualization is rendered as an SVG, generated with D3.js, leveraging functions like `scaleTime`, `scaleLinear`, `axisLeft`, `axisBottom`, and `area` with `curveBasis` to create the smoothed area chart. Data is loaded from an external CSV file containing timestamps and temperature values, which are parsed and mapped to the chart’s coordinates. The chart includes a title and styled axes with rotated labels for enhanced readability.
