This stylized line chart visualizes daily Air Quality Index (AQI) values for Bangor in 2022 over time. Each data point is rendered as a small circle with a hover tooltip, while the connecting line is drawn using D3’s `line` function with a natural curve. The visualization is built with React and D3 v5, using `scaleTime` and `scaleLinear` for the axes, and rendered as an SVG. The data is loaded from a CSV source via D3’s `csv` parser, and the chart is styled using the Poppins font and a custom color palette.
