In this paper, we develop the python code for generating unit graph G (Z₍₌), for any integers m\ \& \ n. For any prime r, we construct r-ary linear codes from the incidence matrix of the unit graph G (Z₍₌), where n \ \& \ m are either power of prime or product of power of primes. We also prove the minimum distance of dual of the constructed codes as either 3 or 4. Finally, we state conjectures two on linear codes constructed from the unit graph G (Z₍ Z₌), for any integer m\ \& \ n.
