We construct an embedding of any right-angled Artin group G(Δ) defined
by a graph Δ into a graph braid group. The number of strands required
for the braid group is equal to the chromatic number of Δ. This
construction yields an example of a hyperbolic surface subgroup embedded in a
two strand planar graph braid group.Comment: 8 pages. Final version, appears in Geometriae Dedicata
