  Using recent experimental data, we analyze the electromagnetic transition
from the nucleon to the P11(1440) resonance. From the resulting empirical
transition form factors, we map out the quark transverse charge densities which
induce the N to P11(1440) transition. It is found that the transition from the
proton to its first radially excited state is dominated by up quarks in a
central region of around 0.5 fm and by down quarks in an outer band which
extends up to about 1 fm.
