I'd like to layout my nodes like a file directory tree:
- root (level 0) node is the top-left node
- level 1 nodes are below the root node, slighlty on its right
- level 2 nodes are below their parent node, slightly on its right, etc.
The closest I found is the BPMN layout. I get the root node at the top but on the same horizontal line as its first child node. I'd like the first child node to be slightly below (actually a bit more that the vertical size of the edges).
How do I get that layout?
