This interactive pie chart visualizes student retention outcomes, breaking down the target variable into two categories: "Retained" and "Dropped." The visualization uses a D3.js v7 SVG rendering with animated hover effects that expand the selected arc segment. The tooltip reveals the exact student count and percentage for each outcome. Data is loaded from a CSV file containing student enrollment attributes, with the target column automatically identified as containing only binary values. The chart employs D3's pie layout, arc generator, and ordinal color scale for categorical distinction.
