The chart output node provides 22 pre-built templates across 6 categories. Selecting a template pre-fills the chart configuration panel. All fields can be adjusted after applying the template. Templates are identified by a templateId stored on the chart config for traceability.
Template Categories
| Category | Template Count | Description |
|---|
| Entity Composition | 5 | Visualise entity structure: property counts, archetypes, status, and relationships. |
| Governance and Compliance | 5 | Visualise PII exposure, classification heatmaps, encryption and masking coverage. |
| Data Quality | 2 | Visualise quality rule coverage and distribution. |
| Structural | 5 | Visualise key distribution, property types, nullable fields, indexing, and foreign keys. |
| Relationships | 1 | Visualise entity connectivity and relationship counts. |
| Summary KPIs | 4 | Single-value gauge charts for high-level governance and quality metrics. |

Chart Types Reference
The 5 chart types supported by the chart output node.
| Chart Type | Renderer | Compatible Data Modes | Description |
|---|
| bar-horizontal | ECharts (SVG) | per-entity, distribution | Horizontal bars. Good for ranked lists with long labels. |
| bar-vertical | ECharts (SVG) | per-entity, distribution | Vertical bars. Good for time series and short labels. |
| stacked-bar | ECharts (SVG) | stacked-per-entity | Vertical stacked bars showing composition breakdown per entity. |
| donut | ECharts (SVG) | distribution | Ring chart showing proportional distribution of categories. |
| gauge | ECharts (SVG) | gauge | Single-value percentage gauge. Shows a ratio as a dial from 0% to 100%. |
