Graphviz will do this. (www.graphviz.org)
The basic (dot) syntax for what you describe below is:
digraph G {
R1 -> VLAN100;
R2 -> R1;
SW1 -> VLAN100;
SW2 -> R2;
H1 -> SW1;
H2 -> SW1;
H3 -> SW2;
H4 -> SW2;
}
It'll output a GIF flowchart-style diagram with the nodes connected as
described above.
It's also good for visualizing BGP AS paths .

I'd like to put a second request. I often want to very quickly
mock-up a diagram that I'm going to use for myself or for internal
purposes.
Is there any application that takes some kind of *simple* description
and produces a (possibly not so beautiful) picture? For example, I
might say something like:
Router(rtr1) connects to vlan 100
Router(rtr2) connects to Router(rtr1) via T1
switch(sw1) connects to vlan100
switch(sw2) connects to Router(rtr2)
A few hosts connect to Switch(sw1)
A few hosts connect to Switch(sw2)
