This example shows a node-link diagram where event nodes connect to attribute nodes such as eventName, index, and traceId, with a toggleable view that disconnects all attributes from their parent entities. The visualization uses WebCola’s `d3adaptor` for constrained layout, rendering nodes and links as SVG elements within a zoomable `g` group. Node colors are loaded from a JSON theme file, with distinct palettes for entities, attributes, relations, and shadows. Pressing the spacebar triggers the disconnection or reconnection of attribute links, updating the layout live via `restart()`.
