Section 2.1.1 says:

In NBMA mode, OSPF emulates operation over a broadcast
network: a Designated Router is elected for the NBMA
network, and the Designated Router originates an LSA for the
network. The graph representation for broadcast networks and
NBMA networks is identical. This representation is pictured
in the middle of Figure 1a.

It should say:

In NBMA mode, OSPF emulates operation over a broadcast
network: a Designated Router is elected for the NBMA
network, and the Designated Router originates an LSA for the
network. The graph representation for broadcast networks and
NBMA networks is identical. This representation is pictured
in the bottom of Figure 1a.

Notes:

The bottom, not middle, of Figure 1a depicts the identical graph representation of broadcast and NBMA networks.
