ttl3d turns RDF (Turtle, N-Triples, RDF/XML, JSON-LD, TriG, N-Quads) or a SPARQL CONSTRUCT result into a single self-contained HTML page that shows the graph in 3D or 2D, with a legend, label search and a detail card per node. The page inlines all of its JavaScript (a bundle of three.js and force-graph, whose licenses ship in ttl3d/vendor/LICENSES.md), so it opens from disk and works offline. A Python API shows the same page inline in Jupyter.
