# - Group related elements
# - Use colors to indicate different layers
# - Add clear labels and descriptions
# - Show data flow direction with arrows

Flowcharts and Process Diagrams

# Flowchart symbols:
# - Rectangle: Process step
# - Diamond: Decision point
# - Ellipse: Start/end point
# - Parallelogram: Input/output
# - Circle: Connector

# Flowchart tips:
# - Start with high-level flow
# - Add detail progressively
# - Use consistent symbol meanings
# - Keep text concise
# - Test the logic flow

Wireframes and Mockups

# Wireframe elements:
# - Rectangles: Content areas, buttons
# - Lines: Dividers, borders
# - Text: Labels, content placeholders
# - Arrows: User flow, interactions

# Wireframe best practices:
# - Focus on layout, not visual design
# - Use grayscale colors
# - Include navigation elements
# - Show content hierarchy
# - Indicate interactive elements
```### Mapas Mentais e Brainstorming
