graph_cytoscape

block

Summary

builds cytoscape elements and stylesheet from a generic node / edge slice.
registers batch layout options ( fcose, cola, breadthfirst, circle, concentric, grid, random ) and seeds positions for new nodes.
exposes CompoundBasis ( single-membership folder tree ) and GroupBasis ( flat multi-membership ) as grouping inputs.
per graph-cytoscape.ts and graph-theme.ts.
getLayoutConfig sets fit: false for initial ( mode = = = ' initial' ) batch layouts so auto_reframe owns the first viewport fit; relayout modes may still fit via the layout algorithm.

Ancestor context

auto_reframe

The graph should automatically fit to the viewport when the loaded node set changes — without requiring the user to click " Fit to view ". After each successful syncSlice, GraphCyController compares the sorted node-id set of the incoming slice with fittedNodeSetKey ( the set the viewport was last fitted to ). When they differ, finishRender triggers an automatic reframe via reframeToViewport. Triggers when any node is added or removed from the slice ( new neighbourhood, focus change, filter change that changes membership ). Does not trigger for metadata-only updates on the same node ids ( label, colour, isCenter flag, etc. ) — those keep the user's current pan / zoom. Does not trigger on requestLayout relayout when the node-id set is unchanged.
