This example visualizes weekly temperature trends in San Francisco using a smooth, stylized line chart with circular data points. The chart displays temperature over time, with axes labeled "Time" and "Temperature" and tooltips showing the day of week for each point. Built with React and D3 v5, it uses `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` with `curveNatural` to render the path. SVG rendering with custom axis components and data from the Sense Your City Dataset provide the interactive visualization.
