Qiskit allows us to build a circuit, having a draw utility that makes it easy to immediately see the results.
Example
from qiskit import QuantumCircuit
circuit = QuantumCircuit(2)
circuit.h(0)
circuit.cx(0,1)
circuit.measure_all()
circuit.draw('mpl',fold=-1)Running the above, we get the resulting circuit
