This visualization displays the temperature in San Francisco over time, using a line chart with points to show daily measurements. The data is loaded from a CSV file using D3’s `csv` utility, and the plot is rendered as an SVG via a React component. The x-axis represents time, formatted with `timeFormat(‘%a’)`, while the y-axis shows the temperature scale. The chart uses `scaleLinear` and `scaleTime` for scaling, and the line is drawn with `curveCardinal` smoothing.
