In the dot language of Graphviz, it could be stated like this:

digraph parsetree {
	node [shape = circle];
	edge [dir = none];

	star [label="*"];
	plus [label="+"];
	minus [label="-"];
	n1 [label="1"];
	n2 [label="2"];
	n3 [label="3"];
	n4 [label="4"];

	plus -> {n1 n2};
	minus -> {n3 n4};
	star -> {plus minus};
}


Which would look like the attached image:
