This visualization shows temperature over time in San Francisco, plotting timestamp values on the x-axis and temperature readings on the y-axis. A smooth basis curve connects the data points, with semi-transparent circles marking individual measurements. The chart uses D3’s `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to build the axes and grid, while `curveBasis` generates the line path. Data is loaded from a CSV file via `csv()`, and rendered as SVG with styled axis labels and gridlines.
