A stylized line chart visualizes weekly temperature trends in San Francisco from the Canvas Sense Your City dataset. The visualization renders temperature readings over time, with circular marks for each data point and styled axes labeled "Temperature" and "Time." Built with React and D3 v5, the code uses `scaleLinear` and `scaleTime` for axes, `csv` for data loading, and displays tooltips via SVG `<title>` elements. The chart employs a Poppins font, teal circular markers, and custom axis styling to create a clean, modern aesthetic.
