This interactive force-directed network visualization displays character relationships from Les Misérables, with nodes colored by community group and links sized by connection strength. Built with D3 v4, it includes a dropdown filter to select character groups, highlighting connected nodes and links while fading others. Nodes can be dragged to reposition, double-clicked to release them back to the physics simulation, and hovered to reveal tooltips with character names, group IDs, or link source/target/strength. The visualization uses SVG with animation, a categorical color scheme from d3-scale-chromatic, and a legend to map group colors.
