This tells you that a required (operating system level) utility
(named "dot") is not available.

Carefully read the installation instructions, especially any
remark about dependencies. This should tell you where "dot" is supposed
to come from. Install all operating system level dependencies.

If "dot" should have come from "graphviz", then maybe a
"hash" is necessary to let your shell see new commands.
