This interactive bar chart visualization, built with React and D3.js v7, displays airline rating data from a CSV file, allowing users to sort, filter, and group ratings by various metrics like seat comfort or overall rating. The visualization supports multiple modes, including a comparison view that overlays bars for two selected airlines across different rating categories, and a time-series line chart showing rating trends over dates. Users can adjust the number of airlines displayed, search for specific carriers, and switch between average, median, or mode aggregation methods. The implementation uses D3's `scaleBand`, `scaleLinear`, `scaleTime`, and `group` functions, with interactive tooltips and animated transitions.
