This stacked bar chart visualizes sales comparisons across different market segments (Consumer, Corporate, Home Office) for various product sub-categories. The visualization uses an interactive SVG rendering with a color legend that allows users to highlight specific segments. Built with D3.js, the chart employs the `d3.layout.stack` API to create stacked bars, with tooltips via `d3-tip` to display precise sales values. The data is sourced from a categorized CSV file showing sales totals, and the chart animates when rendering layers.
