Two trees are in the same row (left to right). How can I display them in the different rows (up to down)? Thank you in advance. Current code displayed image link: https://i.stack.imgur.com/cpJcZ.jpg
digraph {
graph [layout = dot, rankdir = TB]
subgraph n_1{
node [shape = rectangle]
rec1 [label = 'N=370']
rec2 [label = 'Age<=20']
rec3 [label = 'Age>20']
rec1 -> rec2 rec1 -> rec3
}
subgraph n_2{
node [shape = rectangle]
rec4 [label = 'N=102']
rec5 [label = 'Education<=7']
rec6 [label = 'Education>7']
rec4 -> rec5 rec4 -> rec6
}
