This example demonstrates a force-directed graph of character relationships from *Les Misérables*, rendered as an interactive SVG network. The visualization uses `d3.forceSimulation` to position nodes and links, with drag support via `d3.drag` for user manipulation. Node colors encode character groups using `d3.scaleOrdinal` and the `d3.schemeTableau10` palette, while link weights reflect connection strength. The code loads data from a local `miserables.json` file and builds the visualization with D3 v5's selection and join methods.
