This fork displays a week of temperature data for San Francisco as a smooth line chart, from a Data Canvas dataset. D3 v5’s `scaleTime` and `scaleLinear` map timestamps and temperatures to SVG coordinates, while `axisBottom` and `axisLeft` render labeled grid axes. The `line` generator with `curveBasis` draws the curved path, and the SVG titling and styling come from appended text elements and CSS classes.
