A stacked bar plot displays the distribution of three categories—Process, People, and Technology—across five company departments, with horizontal bars scaled by the number of employees. Hovering over a segment highlights it and shows a tooltip with the exact category and count. Built with D3 v7, the visualization uses `d3.stack`, `d3.scaleBand`, and `d3.scaleLinear` to position rectangles within an SVG, while an ordinal color scheme assigns distinct hues. Data is loaded from a local CSV file, and the chart includes labeled axes and a legend.
