This chart displays temperatures recorded in San Francisco over time. The line chart uses a time-scaled x-axis and a linear y-axis for temperature values. The code utilizes the D3.js v7 library, importing functions such as `scaleTime`, `scaleLinear`, `axisBottom`, and `line` to construct the visualization. A smooth basis curve is applied to the path. The data is loaded from a CSV file, parsed with timestamps converted to Date objects, and rendered as an SVG with custom styling for the line, axes, and labels.
