Gantt Diagrams

Plan and track project timelines with Mermaid's Gantt diagrams. Ideal for scheduling data pipeline releases, managing model updates, and visualizing task dependencies.

What are Gantt Diagrams?

Gantt diagrams help you visualize project timelines and track task dependencies. For data teams, they're valuable for planning data pipeline releases, scheduling model updates, and managing project milestones. Each task appears as a bar extending from its start date to its end date.

Creating Your First Gantt Diagram

1. Launch DinoAI: From Code IDE, access DinoAI to start creating diagrams.

2. Use a Simple Prompt: Tell DinoAI what kind of Gantt Diagram you want to create. For example:

- "Create a Gantt chart showing my data project timeline with tasks, dependencies, and milestones"

- "Generate a Gantt diagram for my dbt™ model development schedule with phases and deadlines"

- "Build a Gantt chart showing my data pipeline release plan with testing and deployment phases"

1. Get Your Diagram: DinoAI will generate a complete .mmd file with proper Mermaid syntax.

2. Preview Your Work: Click the eye icon (👁️) to preview your diagram in real-time as you edit.

3. Iterate and Refine: Modify the generated .mmd file directly, or ask DinoAI to make specific changes.

Reusable Gantt Diagram prompts for you and your team

You can create custom, standardized .dinoprompts for Mermaid's Gantt that ensure consistency across your data team. See step-by-step guide.

Diagram Syntax Guide

Basic Structure

Task Types

• Regular task: No special prefix

• Critical task: Add crit tag

• Active task: Add active tag

• Completed task: Add done tag

• Milestone: Add milestone tag

Task Dependencies

• after TaskID: Start after another task

• Fixed dates: Specify start and duration

• Duration units: d (days), h (hours), m (minutes)

Data Team Examples

Data Pipeline Release

Model Training Schedule

Best Practices

1. Use clear section names to group related tasks

2. Include key milestones

3. Mark critical path tasks

4. Consider weekends and holidays with excludes

5. Add dependencies between tasks

6. Keep timelines realistic
