This example shows export revenues by transportation mode, using horizontal bars to compare air, maritime, land, and unknown categories. The chart uses D3 v5’s `scaleLinear` for the value axis and `scaleBand` for the categorical axis, with `axisLeft` and `axisBottom` for ticks. Data is loaded from a CSV file and converted to numbers, and the bars are rendered as SVG rectangles with steelblue fill. The visualization explicitly groups bars by mode without sorting, reflecting the raw data order.
