This stylized line chart visualizes temperature data over time, loaded from a CSV file of weekly San Francisco temperatures. The chart uses a smooth natural curve to connect data points, with dot markers that display tooltips on hover. The visualization is built with React and rendered as an SVG, leveraging D3 utilities like `scaleTime` and `scaleLinear` for axes and the `line` and `curveNatural` functions for the path. The interface uses a custom Poppins font and a teal color scheme for visual appeal.
