This line chart displays weekly temperature readings from San Francisco, plotting time on the x-axis and temperature on the y-axis. The visualization uses React with d3.v7 scales (scaleTime and scaleLinear) and the d3.line path generator with curveNatural to render a smooth curve, while circles mark each data point. Native SVG titles provide simple hover tooltips showing the weekday. Axes are built using custom React components that leverage d3’s tick generation with formatted time labels and grid lines.
