SciGraphs is an open-source Blender extension for graph ingestion, analysis, and 3D rendering. Networks become native Blender objects driven by Geometry Nodes, and analytical results (centralities, communities, topological invariants) are stored as named attributes that drive color, scale, and animation. Analysis comes from NetworkX, igraph, and Graphviz; rendering from Cycles and EEVEE. Node positions come either from a layout algorithm or from the data’s own coordinates: geospatial, sparse-matrix, mesh, or the multi-layer urban graphs the City2Graph module builds.
