This example visualizes clustering patterns in a small dataset where each circle represents an ID with categorical attributes like Location, Group, Class, and Type. Users can click toolbar buttons to group the bubbles by any of these categories, causing the force simulation to reposition clusters around labeled axis points, or return to a single central cluster with “All.” The interactive visualization uses d3.forceSimulation with collide, charge, and positional forces, plus d3.drag for moving individual circles. Data loads from a local CSV file, and circles render as SVG elements with ordinal color scaling.
