You can also set:

    layout = neato;

in a dot file, call dot, and it will use the neato layout engine.

(See https://graphviz.org/docs/attrs/layout/)

And if I look in my /usr/bin, I see that neato is just symlinked to dot. It's pulling the usual trick of one executable that behaves slightly differently depending on the invocation name.
