Overview

Create Dataflow Diagram helps you visually map data movement across systems using Excalidraw. It produces a clear, shareable diagram that highlights data sources, transformations, storage, and destinations. The process starts by reading ./instructions.md and ends with validation against ./checklist.md to ensure completeness.

How This Skill Works

The workflow begins by referencing ./instructions.md to guide diagram requirements, then you build the data flow diagram in Excalidraw following those guidelines. Upon completion, you validate the diagram against ./checklist.md to ensure all criteria are met.

When to Use It

• Document a new data pipeline in your project
• Map data flow during system redesign or integration
• Explain data sources and sinks to stakeholders
• Create a reproducible data-flow reference for audits
• Share a lightweight diagram for onboarding new team members

Quick Start

1. Step 1: Open a new Excalidraw canvas for the diagram.
2. Step 2: Read ./instructions.md to understand requirements and constraints.
3. Step 3: Build the diagram and then validate against ./checklist.md.

Best Practices

• Start with high-level data sources and sinks before detailing transformations
• Label all data flows with clear names and units where applicable
• Keep arrow directions consistent and avoid crossing lines when possible
• Follow instructions.md for diagram requirements and use the checklist.md for validation
• Save or export the diagram from Excalidraw and share the file with stakeholders

Example Use Cases

• Map user data flow from frontend to backend services and database
• Illustrate an ETL pipeline from raw data lake to curated tables
• Show API data exchange between microservices and third-party integrators
• Document a data backup and disaster recovery data path
• Visualize analytics data movement from ingestion to dashboards
