A line chart displays temperature over time for one San Francisco week from the Data Canvas Sense Your City dataset. The visualization uses React to render SVG shapes, with D3 v5 providing scales, axis ticks, and the line path generator with a natural curve. Data loads asynchronously via d3.csv, and time is formatted on the x-axis using timeFormat. The chart omits individual data points and shows only the smoothed line, with axis labels for both dimensions.
