Graph view updated
This explorer contains six saved paper fixtures, not a live bibliographic dataset. A node survives when its year is no later than the selected maximum and at least one of its themes is checked. In an illustrative all-theme view, a maximum year of two thousand six retains three records; two thousand eighteen retains all six. The two expanding bars share fifty pixels per record, giving one hundred fifty and three hundred pixels. The same logical rule then keeps an edge only if both endpoint identifiers survive. This is an induced subgraph, not proof of intellectual influence, bibliographic completeness or current citation counts. Displayed node diameter follows twenty five plus point three five times the square root of the saved citation count, then is clamped to thirty five through eighty. Illustrative counts of one hundred and ten thousand produce raw sizes twenty eight point five and sixty, so their final diameters are thirty five and sixty. Counts of zero and one hundred both hit the same minimum; sufficiently large counts share the eighty maximum. The two growing bars use four screen pixels per diameter unit, reaching one hundred forty and two hundred forty pixels. The square-root transform compresses differences, while clamps erase differences outside the limits. These examples explain code geometry rather than ranking scholarly quality. The saved citation and co-author lists each contain four edges with the same endpoint pairs. Switching the mode changes selected edge metadata, without adding endpoint pairs in this fixture. Both bars therefore measure four at fifty pixels per edge, reaching two hundred pixels. In this strictly offline preview, the external Cytoscape library is unavailable. Initialization safely returns when it is missing, and other handlers still bind. Native presets change checked themes; the year slider updates its label, and the mode switch changes its text. Graph rendering and both export functions return because no graph instance exists. The video preserves this limitation rather than claiming a successful graph or download. Saved fixture relationships and citation counts are not externally verified.
