+
+Content expands from a central axis to both sides.
+
+## Structure
+
+- Central vertical or horizontal axis as the spine
+- Content branches symmetrically or asymmetrically to both sides
+- Axis may be a timeline, process line, or dividing element
+- Creates a balanced, mirrored or complementary layout
+
+## Best For
+
+- Comparison with a shared baseline
+- Timeline with events on both sides
+- Cause-and-effect diagrams
+- Pros/cons with a central divider
+
+## Visual Elements
+
+- Prominent central axis line
+- Content blocks extending to both sides
+- Arrows or connectors from axis to content
+- Optional color coding for each side
+
+## Text Placement
+
+- Axis labels along the center line
+- Content labels beside each branch
+- Title at the top of the axis
+
+## Recommended Pairings
+
+- `corporate-memphis`: Balanced business diagrams
+- `technical-schematic`: Engineering axis diagrams
+- `paper-collage`: Organic branching layouts
