This bar chart visualizes 150 product values across four groups (A–D), sorted descending to compare item magnitudes. Built with D3 v7, it uses `d3.csv` to load `ice6_products_150.csv`, `d3.scaleBand` and `d3.scaleLinear` for axes, and `d3.schemeTableau10` for group colors. Hovering reveals a tooltip with product, value, and group details; bars are SVG `<rect>` elements with a hover transition, and the chart includes rotated x-axis labels and a legend.
