This paper focuses on the numerical study of the collective dynamics of nonlocally coupled Josephson junctions (JJ) driven by Wien bridge oscillators (JJSWBOs). A single JJSWBO exhibits monostable and bistable chaotic behaviors, bistable period-3 oscillations, and a coexistence of regular and chaotic dynamics. To explore the network's collective dynamics, the local dynamics are set in a bistable regime, with initial conditions ensuring random distribution of units on these two types of behavior. Increasing the coupling strength transitions the network from complete incoherence to coherent traveling waves via a chimera state.
