This interactive bar chart visualizes airline ratings from a CSV dataset, letting users compare overall and category-specific scores across airlines. The chart supports sorting, top-N filtering, average/median/mode aggregation, search, and a compare mode that displays side-by-side bars for two selected airlines. A time-series mode plots rating trends over dates using a line chart with grid lines and grouped aggregation. Built with React state management and D3 v7 scales, axes, transitions, and tooltips, the visualization animates bar updates and dynamically adjusts the SVG height based on the number of displayed airlines.
