This interactive visualization displays a hierarchical graph of event data, with nodes representing entities and attributes connected by a force-directed layout using the WebCoLa constraint-based layout library within a React and D3.js v4 framework. It supports zooming and panning via D3’s zoom behavior, and a “Collapse Group” button enables grouping of related nodes. The visualization uses SVG rendering and color themes loaded from a `colors.json` file, applying distinct color scales for entities, attributes, relations, and shadows to highlight data structure.
