This scatter plot visualizes airline review ratings over time, with each circle representing an individual passenger review dated between 2015 and 2019. The x-axis displays review dates using a time scale, while the y-axis shows overall ratings from 1 to 9, with points colored red to green via `d3.scaleLinear` to indicate lower and higher scores. The visualization renders using React 19 and D3 v7, leveraging `scaleTime`, `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` for scales and axes, with a custom `parseDate` function handling various date formats including standalone years. Data comes from a CSV file of airline reviews with missing attribute values converted to zero.
