This interactive graph layout demonstrates filtering of connected nodes using d3.forceSimulation, forceLink, and forceManyBody to position nodes with color-coded clusters. A color legend and check button allow users to select specific node groups by clicking legend circles or toggling layer display, which triggers node resizing and edge visibility updates. The visualization uses precomputed x, y, and k coordinates from CSV data, rendered as SVG circles and lines with animated transitions lasting one second.
