This line chart displays weekly temperature variations over time, with a smooth curved line connecting individual data points plotted on Cartesian axes. Built with React and D3.v7, the visualization renders as SVG, using `scaleTime` and `scaleLinear` for the temporal and temperature scales, `curveNatural` for the line path, and `csv` to load the San Francisco temperature dataset. Axis ticks, gridlines, and circle markers with tooltips provide detailed reading of the values.
