This grouped barplot visualization compares three conditions—Nitrogen, normal, and stress—across four crop groups in a CSV dataset. The D3.js chart renders each group as a cluster of colored bars using `d3.scaleBand` and `d3.scaleOrdinal`, with SVG rectangles for the bars. A tooltip built with D3's `select` and `dispatch` shows values on hover, while smooth transitions animate bars into place on load. The reusable component pattern exposes setters for data, dimensions, and colors, as seen in the `multiBarplot` and `barplot` modules.
