This visualization displays one week of temperature readings in San Francisco as a line chart, with time on the x-axis and degrees Celsius on the y-axis. The chart uses a smoothed, curved line to represent temperature trends over the period. Built with D3 v5, the code employs `scaleTime` and `scaleLinear` for axes, `line` with `curveBasis` for the path, and `axisLeft` and `axisBottom` for tick marks. Data comes from the Data Canvas - Sense Your City dataset, rendered as SVG elements with custom styling for ticks and labels.
