Prevent node overlap in Mermaid diagrams by applying layout-control techniques like invisible anchors, arrow-length hacks, and subgraph grouping to ensure predictable rendering and consistent spacing without manual dragging.

An invisible anchor in Mermaid uses the ~~~ syntax to keep nodes on the same rank without drawing a visible line, providing precise layout control to align elements and prevent misalignment in graph TD and graph LR diagrams.

Increase spacing between nodes in a Mermaid graph by using the arrow-length hack with extended dashes like ----, which increases spacing along the main spine to improve diagram readability and comprehension.

Node definition ordering establishes priority in top-to-bottom rendering within Mermaid diagrams, allowing you to control the visual layout hierarchy and ensure predictable visual structures.

Group related nodes using subgraph force fields in Mermaid to prevent external lines from weaving through the grouped nodes, maintaining a clean and organized diagram layout for documentation visuals.

The best way to align several nodes on the same level in Mermaid is by using multi-node connections combined with invisible anchors, ensuring precise horizontal or vertical alignment across the diagram.
