Example 3: Using Groups

Organizing nodes into logical groups:

vgraph project_planning: IBIS "Project Planning" {
    node main_q: Question "How should we structure the project?" [fontsize: 20];

    group architecture "Architecture Decisions" {
        style: filled;
        color: lightblue;

        node q1: Question "Which architecture pattern?";
        node a1: Answer "Microservices";
        node a2: Answer "Monolithic";

        edge q1 -> a1;
        edge q1 -> a2;
    };

    group testing "Testing Strategy" {
        style: filled;
        color: lightgreen;

        node q2: Question "What testing approach?";
        node a3: Answer "TDD";
        node a4: Answer "BDD";

        edge q2 -> a3;
        edge q2 -> a4;
    };

    edge main_q -> q1: answered_by "Consider architecture";
    edge main_q -> q2: answered_by "Define testing";
}
