This fork of Curran’s working-with-time example visualizes a week of San Francisco temperature readings from the Data Canvas Sense Your City dataset. The vertical axis shows temperature in degrees, while the horizontal time axis is formatted by day of the week. React renders SVG marks and axes, with d3.scaleTime and d3.scaleLinear mapping the data, d3.line with curveNatural drawing the smooth path, and d3.csv loading the remote CSV file.
