Suggested Questions

Questions this graph is uniquely positioned to answer:

• Why does FenParserFastParse connect Community 6 to Community 3? High betweenness centrality (0.004) - this node is a cross-community bridge.
• What connects PieceTest, PieceTypeTest, SquareTest to the rest of the system? 55 weakly-connected nodes found - possible documentation gaps or missing edges.
• Should Community 0 be split into smaller, more focused modules? Cohesion score 0.11 - nodes in this community are weakly interconnected.
• Should Community 1 be split into smaller, more focused modules? Cohesion score 0.09 - nodes in this community are weakly interconnected.
• Should Community 2 be split into smaller, more focused modules? Cohesion score 0.11 - nodes in this community are weakly interconnected.
• Should Community 3 be split into smaller, more focused modules? Cohesion score 0.09 - nodes in this community are weakly interconnected.
• Should Community 4 be split into smaller, more focused modules? Cohesion score 0.14 - nodes in this community are weakly interconnected.
