This stacked bar chart visualizes the distribution of four numeric values (A–D) across eight animal species, with each bar’s segments colored by the animal’s group (Domestic, Pest, Africa, or Marine) rather than by the series itself. The animation on load slides the bars into place from the right, with each segment transitioning in width and position. Built with D3.js v5 and rendering SVG, it uses `d3.stack()`, `d3.scaleBand()`, `d3.scaleLinear()`, and `d3.scaleOrdinal()` to map data from a CSV file, while each group receives its own color palette defined through a custom ordinal scale.
