# d-separation explorer

Two variables are d-separated given a set when every path between them is blocked. Choose two
variables and what to condition on: conditioning blocks a chain or a fork, but opens a path through
a collider when the collider or one of its descendants is in the set. Each answer comes from
Andrey's d-separation oracle.
