A space is $n$-arc connected ($n$-ac) if any family of no more than $n$-points are contained in an arc. For graphs the following are equivalent: (i) $7$-ac, (ii) $n$-ac for all $n$, (iii) continuous injective image of a closed subinterval of the real line, and (iv) one of a finite family of graphs. General continua that are $\aleph _0$-ac are characterized. The complexity of characterizing $n$-ac graphs for $n=2,3,4,5$ is determined to be strictly higher than that of the stated characterization of $7$-ac graphs.
