This example shows a horizontal bar plot ranking the top 15 airlines by their average overall rating, derived from an airline quality dataset. Bars are color-coded on a red-to-green gradient to reflect rating scores. The visualization is built using React and D3, with D3’s `csv` for data loading, `group` and `mean` for aggregation, and `scaleLinear` and `scaleBand` for scales. Axes and labels are rendered via D3’s `axisBottom`, `axisLeft`, and custom label functions.
