Embedding right-angled Artin groups into graph braid groups

We construct an embedding of any right-angled Artin group $G(\mathrm{\Delta })$ defined by a graph $\mathrm{\Delta }$ into a graph braid group. The number of strands required for the braid group is equal to the chromatic number of $\mathrm{\Delta }$. This construction yields an example of a hyperbolic surface subgroup embedded in a two strand planar graph braid group.
