Drawing Quantum Circuit for Vehicle Routing Protocol (VQE) given in qiskit

Question

I have recently started to explore about Quantum Computing and was looking at Vehicle Routing Protocol using VQE. My aim is to generate a quantum circuit from the above link and I referred to this post in stack-overflow. It shows how quantum circuit can be generated using hamiltonian and ansatz. I did following:

quantum_instance = QuantumInstance(
            BasicAer.get_backend("qasm_simulator"),
            seed_simulator=algorithm_globals.random_seed,
            seed_transpiler=algorithm_globals.random_seed,
        )

vqe = VQE(quantum_instance=quantum_instance)
optimizer = MinimumEigenOptimizer(min_eigen_solver=vqe)

ansatz = EfficientSU2(3)
parameters = list(ansatz.parameters)
op,offset = qp.to_ising() //qp is my quadratic program from qiskit documentation
circuits = vqe.construct_circuit(parameters, op)
for circuit in circuits:
    print(circuit.draw())

I have also tweaked construct_problem to include qp.objective.num_qubits=54. I am not sure if I am approaching it correctly to display the quantum circuit. I must notify that I am a software engineering student and an absolute beginner with quantum computing and any pointers to the right direction will be greatly appreciated.
