This example visualizes weekly temperature readings from the Data Canvas Sense Your City dataset as a stylized line chart. The chart displays temperature over time using a smooth curve, with labeled axes for time and temperature. The code builds the visualization with React components and D3 v5 APIs including `scaleTime`, `scaleLinear`, `line`, and `curveNatural`. It renders as an SVG, using D3’s `csv` loader to fetch data and `extent` to compute domains, with tick marks and axis labels styled via CSS.
