00:00:00.460 --> 00:00:03.626
A diagram should help someone answer a concrete question.

00:00:03.746 --> 00:00:07.266
Start with what calls what, and who owns each responsibility.

00:00:08.427 --> 00:00:10.712
Choose one level of detail before drawing.

00:00:10.832 --> 00:00:14.706
A system overview and a deployment diagram answer different questions.

00:00:15.860 --> 00:00:19.224
In Arc, nodes and connectors live in typed diagram data.

00:00:19.343 --> 00:00:22.970
Labels and reusable connector styles describe the relationships.

00:00:24.127 --> 00:00:28.250
For example, show a client, an API, and a database.

00:00:28.370 --> 00:00:30.754
Label the request path and the data access.

00:00:31.927 --> 00:00:34.769
Keep the configuration beside the code it explains.

00:00:34.889 --> 00:00:40.076
A text diff lets reviewers inspect diagram changes alongside implementation changes.

00:00:41.227 --> 00:00:43.162
A clean diagram is still a claim.

00:00:43.282 --> 00:00:46.125
Check every arrow and boundary against the current system.

00:00:47.927 --> 00:00:51.739
Name the scope, label the connections, and review the diagram.

00:00:51.859 --> 00:00:54.243
Use Arc to keep the explanation editable.
