Looks great! I'm sure you've already thought of these use cases but just in
case two things I'd be worried about with this style of straight lines is:
1. How it looks when a task has a large number of downstream tasks (e.g.
20+)?
2. Is it possible to visually distinguish lines when they have to cross each
other?
The current curve lines means even it's messy the angle always allows you to
distinguish the lines, e.g.:
```python
import datetime
from airflow.models import DAG
from airflow.operators.empty import EmptyOperator
with DAG(
dag_id="test",
schedule_interval="@once",
start_date=datetime.datetime(2000, 1, 1),
) as test:
upstream_tasks = [EmptyOperator(task_id=f"upstream_{i}") for i in
range(4)]
downstream_tasks = [EmptyOperator(task_id=f"downstream_{i}") for i in
range(4)]
for upstream_task in upstream_tasks:
upstream_task >> downstream_tasks
other_tasks = [EmptyOperator(task_id=f"other_{i}") for i in range(16)]
upstream_tasks[0] >> other_tasks
```
