How to draw diagonal lines?

[HariSekhon]

Is it possible to draw diagonal lines, for example, something analagous to this:

rather than this:

from diagrams import Diagram, Edge
from diagrams.programming.flowchart import Action
 
with Diagram('Release Straight to Production!', direction='BT'):
    prod = Action("Prod")
    for _ in range(1, 4, 1):
        Action("Dev") >> Edge(label=f"Feature {_}") >> prod

which looks really ugly:

2. It's not clear to me why the arrows in this case don't go anywhere near the boxes.

I've done a couple other diagrams and played with all the examples and they don't come out anywhere near as ugly as this (this is the first time I'm trying to do a workflow with the programming node set):

I guessed from the C4 doc to add splines graph_attr:

from diagrams import Diagram, Edge
from diagrams.programming.flowchart import Action
 
graph_attr = {
    "splines": "spline",
}

with Diagram('Release Straight to Production!', direction='BT', graph_attr=graph_attr):
    prod = Action("Prod")
    for _ in range(1, 4, 1):
        Action("Dev") >> Edge(label=f"Feature {_}") >> prod

which gets me closer:

Now why is there such a huge distance between the boxes and the arrows?

I ended up moving to D2 and getting a better result quite easily:
