- Implement all helper functions in ex01_network_viz.py: - ensure_exists(): validate input files exist - read_expression_matrix(): load CSV with gene index - read_modules_csv(): parse module mapping to dict - correlation_to_adjacency(): compute Spearman correlations with threshold - graph_from_adjacency(): convert to NetworkX graph, remove isolates - color_map_from_modules(): assign tab10 colors by module - compute_hubs(): find top-k genes by degree centrality - Generate outputs: - network_AndreiCod.png: spring layout visualization with module colors - hubs_AndreiCod.csv: top 10 hub genes with degree - Add reflection notes on visualization advantages vs numeric analysis Parameters used (same as Lab 6): - Spearman correlation - Absolute correlations - Threshold: 0.85 Results: 80 nodes, 593 edges, top hub: Gene_55 (degree 20)
