This example presents an interactive interface for querying and exploring a Grakn knowledge graph through a series of linked dropdown menus and type selectors. Users navigate hierarchical data by choosing main and secondary leaves, linking roles, and a third leaf to refine their exploration. The visualization uses React for state management and D3.js v4, rendering SVG elements on a Bootstrap-styled page. It connects to a Grakn database via URL and port, executing queries against a specified keyspace, with the graph’s structure updated dynamically based on user selections.
