This visualization displays the sales totals for various product segments, broken down by sub-category, as a stacked bar chart. The chart uses an SVG rendering and includes an animated tooltip that shows the specific sales value for a segment when hovered. Built with Vue and D3, the visualization employs `d3.layout.stack` to create the stacked bars, `d3.scale.ordinal()` for the x-axis, and `d3.legend.color` for the interactive legend that isolates individual sub-categories. The data originates from a CSV file containing sales figures.
