- Remove thinc direct constraint from nlp-spacy in pyproject.toml and update README/CHANGELOG
- Raise ProcessingError with install hint when UMAP is requested but unavailable in EmbeddingVisualizer
- Guard PCA and TSNE dimensionality reducers against None with actionable error messages
- Prevent keyword collisions in EmbeddingVisualizer dimensionality reduction (_reduce_dimensions)
- Add core-only install & test step to .github/workflows/ci.yml using base-deps.txt
- Prevent AttributeError on module load in repo_ingestor.py and xml_ingestor.py when optional dependencies are absent
- Make TOML loading in tests/test_issue_1513_slim_core.py portable across Python versions via UTF-8 text decode and loads
- Expand slim-core test suite to 17 test cases covering 2D/3D projections, core imports, and options handling
* test(visualization): isolate optional dependency mocks
* test(visualization): stop requiring Plotly in unit tests
Removing the global sys.modules stubs left the tests that patch
`...go.Bar`, or call a visualizer, with nothing standing in for the
module level `px` and `go` aliases. Those are None when Plotly is
missing, so patch resolution and _check_dependencies() both failed.
Add a helper that substitutes a double only for the aliases that are
None, leaving the real module in place when Plotly is installed.
---------
- Add semantica/kg/knowledge_graph.py with KnowledgeGraph dataclass
(entities, relationships, metadata) plus __len__ and __bool__ helpers
- Export KnowledgeGraph from semantica/kg/__init__.py
- Add KGVisualizer._convert_knowledge_graph() for explicit, non-mutating
conversion from KnowledgeGraph to internal dict format
- Route isinstance(graph, KnowledgeGraph) through _convert_knowledge_graph
inside _normalize_graph so all five visualize_* entry points accept
KnowledgeGraph directly without any manual conversion
- Add TestFormalKnowledgeGraphType (15 tests)
Closes#471
KGVisualizer.visualize_network() (and sibling methods) only accepted a raw
dict. Passing a KnowledgeGraph object — the natural output of
GraphBuilder.build() — silently returned without rendering.
Added _normalize_graph() which duck-types the input: dicts pass through
unchanged; any object exposing .entities / .relationships attributes is
converted to the canonical dict form; anything else raises a clear
ProcessingError naming the offending type.
_normalize_graph() is called as the first statement in visualize_network(),
visualize_communities(), visualize_centrality(), visualize_entity_types(),
and visualize_relationship_matrix().
Also adds 21 tests in tests/visualization/test_kg_visualizer_normalize_graph.py
covering the helper directly, the end-to-end regression for #458, and
a guard that every public method routes through _normalize_graph.
