 - Each PDF provides the call graph computed with Salsa, where we can see it is capable of adding edges to call back methods;
 - Nodes in light green are *application nodes*, nodes in light orange are *primordial nodes*, and underlined nodes are *synthetic nodes* added by Salsa to handle the call backs during serialization/deserialization; 
-- Each node is preceded by an `id` number to avoid labels to be duplicated (when a same method is invoked multiple times in an application).

 - Please notice that each PDF has only a **subset** of nodes and edges from the original call graph because each call graph includes many nodes from API calls.
