Warning: using box for unknown shape cylinder

[trstruth]

Hey, this is a great idea for a tool!

I've run into an issue while trying to create a database component.
Using the following yml input:

title: Title
backgroundColor: '#ffffff'

components:
  -
    kind: database
    label: DB

Throws a warning when I try to generate a png:

$ draft issue.yml | dot -Tpng > repro.png
Warning: using box for unknown shape cylinder

The generated png shows the db component as a box instead of a cylinder:

I installed draft via something like

go get -u https://github.com/lucasepe/draft/issues/new
cd $GOPATH/src/github.com/lucasepe/draft/cmd
go install
mv $GOPATH/bin/cmd $GOPATH/bin/draft

Any idea what the issue could be here?

Ran the same thing with the binary downloaded from the Releases tab and hit the same behavior

Looks like an issue with the graphviz version I'm using:

$ dot -V
dot - graphviz version 2.38.0 (20140413.2041)

Apparently it's fixed in version 2.39.x and up

Unfortunately it looks like on Ubuntu 16.04, apt-get install -y graphviz installs 2.38. Maybe a note about this in the README might help others. I'll close the issue out now.
