This example visualizes miles per gallon for various motorcycle models as a horizontal bar chart, sourced from the mtcars dataset. It shows the ranking of each model’s fuel efficiency. The code uses React for component rendering, D3 v5’s `scaleBand` and `scaleLinear` for scales, and `csv` to load the data. Bars are drawn as SVG `rect` elements, with axis ticks and grid lines generated using D3’s `ticks` method. The chart displays values up to the maximum mpg, with a light green page background.
