I want two edges to connect to the same point on a node, like in this screenshot:

Using the following simple code the edges always connect to the center of a node, but I want them to connect to a central point under the node. So if the shape were a box instead plaintext the edges should be connecting on a point on the perimeter of the box.

strict graph {

    node [
        shape=plaintext,
    ]

    A
    B
    C

    A -- B
    A -- C
}

I also tried several things using ports but I couldn’t get the desired result. What I want is a binary tree of plain text nodes that always follow the shown pattern – so ideally I wouldn’t have to set the attribute on each node/edge but could specify the necessary attributes at top level for the whole graph.
