I have a small directed graph which is a metadata basically. A single node is a table and an edge in this context means table1 feeds to table2 (query of table2 refers to table1). So when a certain table is impacted for some reason , I want to understand which all downstream tables are affected by this. So if a node A is affected , I want all the nodes reachable from that node. So say the node table is:-
Nodes = {A,B,C,D}
Edges = { (A,B) , (B,C) , (C,D) }
then if A is impacted , I want to see the entire impact list i.e. {B,C,D}.
I should be able to click on a given node in Gephi and it should highlight entire subgraph which the nodes reachable (since it's a directed graph) from the node I clicked on.
