Decision Tree

digraph location {
    start [label="Location / Maps task" shape=ellipse];
    domain [label="Core Location or MapKit?" shape=diamond];
    cl_type [label="Need what?" shape=diamond];
    mk_type [label="Need what?" shape=diamond];

    start -> domain;

    domain -> cl_type [label="Core Location"];
    domain -> mk_type [label="MapKit / Maps"];
