A force-directed bubble chart visualizes a small dataset of 12 items, each with categorical attributes. The visualization initially displays all nodes as colored circles that can be dragged and selected. Buttons allow users to split the bubbles into separate clusters by Location, Group, Class, or Type, with titles indicating the active categories. Using D3 v4, the chart employs `d3.forceSimulation` with `d3.forceCollide`, `d3.forceManyBody`, `d3.forceX`, and `d3.forceY` to position the nodes. The SVG circles and text labels are rendered from a CSV file. Users can interactively drag and select individual bubbles to highlight them.
