Graphviz Example: family tree

// Defining relationships

grandparents -> { parent1 parent2 parent3 };

parent1 -> { child1 child2 };

parent2 -> { child3 child4 };

parent3 -> { child5 };

// Defining individual nodes

grandparents [shape=ellipse, style=filled, color=lightblue, label="Grandparents"];

parent1 [shape=box, style=filled, color=lightgreen, label="Parent 1"];

parent2 [shape=box, style=filled, color=lightgreen, label="Parent 2"];

parent3 [shape=box, style=filled, color=lightgreen, label="Parent 3"];

child1 [shape=ellipse, label="Child 1"];

child2 [shape=ellipse, label="Child 2"];

child3 [shape=ellipse, label="Child 3"];

child4 [shape=ellipse, label="Child 4"];

child5 [shape=ellipse, label="Child 5"];
