This example shows a graph visualization where nodes represent entities and attributes, and groups represent collapsed trace records, each with a distinct color palette. The visualization uses a force-directed layout to position the elements, with rectangular groups and nodes rendered as SVG elements. The code loads data from `graph.json` and `colors.json`, and uses the WebCoLA library via `cola.d3adaptor(d3)` to handle the layout with grouping, link lengths, and overlap avoidance. Dynamic colors are applied to nodes and groups based on the loaded color schemes, and the whole visualization is zoomable.
