This line chart displays weekly temperature data for San Francisco, plotted over time with a linear y-axis and time-based x-axis. The visualization uses React to render SVG elements, with d3.scaleTime and d3.scaleLinear mapping data points to coordinates. The line path and individual circles are generated using d3.line and curveLinear, while custom React components (AxisBottom, AxisLeft, Marks) handle axis tick rendering and data marks. The chart includes labeled axes, gridlines, and a dataset loaded via d3.csv from a remote CSV source.
