To any finite graph
(viewed as a topological space) we associate an explicit compact metric space
, which we call
the reflectiontree of graphs . This space
is of topological dimension
and its connected components are locally connected. We show that if
is appropriately triangulated (as a simplicial graph
for
which
is the geometric realization) then the visual boundary
of the right-angled
Coxeter system
with
the nerve isomorphic to
is homeomorphic to
.
For each
, this
yields in particular many word hyperbolic groups with Gromov boundary homeomorphic to
the space
.
I dedicate this paper to the memory of
my parents.
