OSCAL Visualizer Skill
Create visual representations of OSCAL documents to help understand control structures, relationships, and compliance status.
When to Use This Skill
Use this skill when you need to:
- Visualize control hierarchies and families
- Show component relationships
- Display implementation coverage
- Create SSP overview diagrams
- Generate assessment flow charts
- Produce compliance dashboards
✅ Data Source Principle
This skill creates visualizations from documents you provide. All diagram content reflects your OSCAL data — no compliance information is generated from training knowledge.
Diagram Types
| Type | Purpose | Best For |
|---|---|---|
| Control Hierarchy | Show control families and relationships | Catalogs, profiles |
| Component Relationships | Map components to controls | Component definitions |
| Implementation Flow | Show how controls are implemented | SSPs |
| Profile Inheritance | Display profile layering | Profiles |
| SSP Overview | System security summary | SSPs |
| Assessment Flow | Assessment process visualization | SAP, SAR |
