This stacked bar chart displays the nutritional composition of ten common foods, breaking down proportions of fiber, protein, fat, carbs, and vitamins along a horizontal percentage axis. Hovering over any segment reveals an interactive tooltip showing the exact percentage value. The visualization uses d3.stack() to generate layered bars, with d3.scaleBand and d3.scaleLinear handling positioning, while d3.scaleOrdinal assigns distinct colors to each nutrient category. Data comes from a local CSV file, rendered as SVG elements with mouseover and mouseout events driving the tooltip behavior.
