This line chart visualizes weekly temperature data for San Francisco using React and D3 v5, rendering an SVG with time-scaled axes. The React components `AxleBottom`, `AxleLeft`, and `Marks` leverage D3's `scaleTime`, `scaleLinear`, and `line` API to construct the axes and path. Temperature values are plotted against timestamps, with data loaded from a CSV file via `d3.csv`. The chart includes grid ticks, axis labels, and circles at each data point.
