Hi Chris,

there is one more bug:

from diagrams import Diagram

from diagrams.digitalocean.network import LoadBalancer
from diagrams.digitalocean.storage import Space

from diagrams.digitalocean.compute import Containers

with Diagram("Test", show=False):
LoadBalancer >> Containers >> Space

Traceback (most recent call last):
Containers >> Space
TypeError: unsupported operand type(s) for >>: 'type' and 'type'

If you do this:

from diagrams import Diagram

from diagrams.digitalocean.network import LoadBalancer
from diagrams.digitalocean.storage import Space

from diagrams.digitalocean.compute import Containers

with Diagram("Test", show=False):
LoadBalancer("Test balancer") >> Containers("Test containers") >> Space("Test space")

It works fine. I'm not sure what you posted is actually the correct use, is it?

Oh, I also missed it. Thank you so much.
