This line chart visualizes temperature changes over time in San Francisco over a week. The visualization uses React to render SVG elements, with D3 v7 scales for positioning data points along time and linear axes. The chart displays a smooth curve connecting temperature readings using the D3 line generator with a natural curve interpolation. The data is loaded from a CSV file using D3's csv function, with custom axis components drawing tick marks and labels for both the date and temperature dimensions.
