This network graph visualizes character relationships from the Peppa Pig universe as a force-directed layout. All eight characters from the JSON data appear as purple circular nodes with labels, connected by orange lines that indicate friendship links between characters. The visualization uses D3.js version 6 with `d3.forceSimulation` to position nodes, applying link, charge, collision, and center forces. Users can drag nodes to explore the network, and hovering switches node outlines to green through the `nodeHover` CSS class. The SVG rendering approach is visible in the source code.
