This area chart displays one week of temperature data in San Francisco, sourced from Data Canvas: Sense Your City. The visualization uses a smooth, basis-curved area path to show temperature fluctuations over time, with a time-scaled x-axis and linear y-axis. Built with D3 v6, it leverages `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `area` with `curveBasis` to render the SVG chart, including grid lines and labeled axes. Temperature values are parsed from a CSV dataset and mapped to the chart’s coordinates.
