A smooth line chart displays San Francisco weekly temperature trends over time, using a natural curve to connect data points from the Data Canvas Sense Your City dataset. Built with React and D3 v5, the SVG visualization employs `scaleTime` for the x-axis and `scaleLinear` for the y-axis, with `line.curveNatural` generating the styled path. Axis components render tick marks and labels, while the chart omits individual data points for a clean, minimalist look. Temperature is plotted against timestamps, with Poppins typography and teal stroke styling.
