Backgrounds & Patterns | ERD Generator Docs

The Backgrounds & Patterns settings let you control how your ERD canvas looks and feels. They don’t change your data — they help you see it more clearly.

Whether you’re designing, presenting, or exporting your diagram, the right background improves focus, readability, and visual balance.

✨ What You Can Do

With Backgrounds & Patterns, you can:

  • Change the canvas background style
  • Add or remove visual guides (dots or grid)
  • Adjust spacing and thickness of patterns
  • Tune contrast for light or dark themes
  • Create clean screenshots for presentations

All changes update instantly and only affect the current diagram.

🧩 Background Styles

Plain

A clean, distraction-free canvas with no pattern.

Best for

  • Presentation slides
  • Screenshots and exports
  • Dense diagrams with many tables

Why use it

Keeps full attention on tables and relationships.

Dots

A subtle dotted background that helps with positioning.

Best for

  • Dragging and arranging tables
  • Free-form layouts
  • Long editing sessions

Why use it

Adds gentle structure without visual clutter.

Grid

A structured grid made of horizontal and vertical lines.

Best for

  • Precise alignment
  • Technical reviews
  • Symmetrical or large schemas

Why use it

Makes spacing and alignment feel intentional.

🎚️ Customization Controls

Density

Controls how close or far apart the dots or grid lines appear.

  • Lower density → tighter, more technical look
  • Higher density → open, breathable layout

Tip

Medium density works best for most diagrams.

Thickness

Controls how bold the dots or grid lines look.

  • Thin → subtle and minimal
  • Thick → strong visual guidance

Tip

Keep patterns thinner than table borders for clarity.

Visual Tone (Color)

Choose the color of the background pattern.

Best practices

  • Use soft, muted colors
  • Avoid very bright or saturated tones
  • Match the mood of your diagram (light or dark)

Why this matters

Backgrounds should support your diagram, not compete with it.

🌗 Contrast & Readability

Good contrast makes your diagram easier to understand and share.

Recommended

  • Subtle patterns in the background
  • Clear separation between tables and canvas
  • Softer contrast for dark mode diagrams

If your background stands out more than your tables, reduce its intensity.
