This is a fork of a D3.js line chart that visualizes temperature measurements over time, depicting a week of San Francisco weather data from the Data Canvas Sense Your City dataset. The visualization uses a time-scaled x-axis and a linear y-axis for temperature. The chart is built with React and uses D3's `scaleTime`, `scaleLinear`, and `line` with `curveNatural` to create a smooth path, rendered as SVG.
