Genome Atlas: expanding Sankey view with annotated / not-annotated bars
Reworks the Genome Atlas tree into an expanding Sankey diagram.
Sankey bars. Each group is a bar split into annotated (green) and not-annotated (gray) assemblies. Two-tone flows carry both parts from a parent into its lineages. Bar and flow heights follow assembly counts within a column, and each column is rescaled to the full height so deep lineages stay legible.
Expands to the right. Clicking a group adds its lineages as a new column instead of re-rooting the view, so every ancestor stays visible. Clicking a group in an earlier column replaces the columns after it. The selection is encoded as a path (2759/33154/33208, with ~offset for expanded "Other lineages"), validated server-side, so the view stays stateless. Search and the shortcuts open the full lineage of a taxon. A selected lineage outside a column's top six is pinned into that column. The view auto-scrolls to the newest column.
Other details:
- Event payload key is
route, because Gradio treats apathfield as a file reference. - "← Parent group" is now "← Collapse last group"; breadcrumbs collapse to any ancestor.
- Added
tests/test_taxonomy.py: column expansion, lineage paths, aggregate expansion, invalid-path rejection. The full suite passes (19 tests). - Updated the README and FEATURE_BACKLOG descriptions.
Tested locally in sample mode with Gradio 6.6.0.
