This example visualizes a graph of event entities and their attributes, such as event names and trace IDs, using a force-directed layout with grouped nodes. The SVG rendering uses a custom theme applied from a JSON color palette, with distinct colors for entities, attributes, and relations. The visualization leverages the WebCola layout library via `cola.d3adaptor` for graph positioning, while D3.js v4 handles data loading, node and link rendering, and zoom interactions. Data comes from bundled JSON files containing the graph structure and color schemes.
