This interactive stacked bar chart visualizes the distribution of five fruit types across five quantity bins, from "Below 100" to "Above 400." A radio-button interface toggles between two animation states: step one displays the full stacked bars, while step two separates each category into thinner, individual segments. Built with D3 v4, the visualization uses `d3.scaleBand`, `d3.scaleLinear`, `d3.stack`, and `d3.scaleOrdinal` to map data from a CSV file. The SVG rendering and smooth `.transition()` animations bring the data comparisons to life.
