 Here D is shared between A and B — it appears once with edges from both parents. Each parent's edges are drawn on separate routing rows to avoid visual ambiguity.
 
+## Width Limiting
+
+When a node has many children, the graph can grow very wide. The `maxWidth` parameter constrains the output by wrapping wide layers onto multiple rows. Children that don't fit are moved to additional rows, with vertical connectors routing edges through the intermediate layers automatically.
+
+```java
+GraphNode root = GraphNode.of("Pipeline")
+        .child("Compile")
+        .child("Test")
+        .child("Lint")
+        .child("Package")
+        .child("Deploy")
+        .child("Notify");
+
+// Without maxWidth — all children on one wide row:
+Graph.render(root);
+```
+
+```
+                  Pipeline
+   ┌───────┬─────┬────┴─┬────────┬───────┐
+Compile  Test  Lint  Package  Deploy  Notify
+```
+
+```java
+// With maxWidth=25 — children wrap to fit:
+Graph.render(root, 25);
+```
+
+```
+          Pipeline
+   ┌─────┬──┬─┴──┬───┬────┐
+Compile  │  │  Test  │  Lint
+     ┌───┘  │        │
+     │      └─┐      │
+     │        │      └┐
+  Package  Deploy  Notify
+```
+
+A `maxWidth` of `0` (the default) means no limit. The wrapping applies to the node label layers; routing lines between layers may extend slightly beyond `maxWidth` when connecting nodes across split rows.
