This line chart displays one week of temperature data in San Francisco, with time on the x-axis and degrees Celsius on the y-axis. The chart uses D3 v5’s `scaleTime` and `scaleLinear` to map the data, `axisBottom` and `axisLeft` for labeled axes, and a `line` with `curveBasis` to draw the smoothed temperature path. The data, loaded via `csv` from a dataset on Gray Area’s Data Canvas, is rendered as SVG with styled grid lines, axis labels, and a title.
