This line chart displays San Francisco temperature readings over time, with a smooth curved line plotted against labeled axes for time and temperature. The visualization is rendered as an SVG using React and D3 v5, employing `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to construct the scales and axes. Data is loaded via `csv` from an external dataset, and the line is generated with `line` and `curveBasis`. Grid lines are styled using tick marks, with the chart title and axis labels added as SVG text elements.
