How to set the order of the nodes in one layer by the order of the definition of edges rather than the definition of nodes when using dot to draw a tree diagram?

For example, For some reasons i need to first define node1, node2, and node3, and then draw the edges: node3 -> node2, and node3 -> node1, and i hope that the edges are drawn as they are defined.

below are the .dot files

digraph G {
    node1 [label = 1];
    node2 [label = 2];
    node3 [label = 3];
    node3 -> node2;
    node3 -> node1;
}

fig 1. node2 on the right

but I want it to be like this:

fig 2. node2 on the left

How can i realize this? Thank you for help.
