A national dataset, seen as a knowledge graph.

The same UK NaPTAN data my explorer profiles row-by-row, re-expressed as an ontology — classes (stop types), instances (real stops) and relations (a stop is of type, sits at a locality). Turning flat records into navigable structure is exactly the work behind the GDS ontology generator. Rendered in 3D, in your browser, with three.js.

How it works. A typed graph (nodes + relations) built from the official NaPTAN export is laid out by a force simulation and rendered with WebGL via 3d-force-graph / three.js. Drag to rotate, scroll to zoom, hover for labels, click a node to fly to it and reveal its neighbours. The same shape — classes, instances, relations — is what an ontology gives a search/RAG/governance layer to reason over. Built by John Mikel Regida.
