Graphviz & Charts in Confluence: draw.io, Graphviz Charts, Mermaid — Comparison (2026)
Teams use Confluence to document architecture, processes, and organizational structures. But Confluence doesn't render graphs or charts natively — you need a marketplace app.
We built Graphviz Charts for Confluence to bring the power of Graphviz and DOT language to Confluence pages. In this post, we compare it against every alternative.

Feature Comparison
draw.io
What it does: Full diagramming tool embedded in Confluence.
Strengths:
- 100+ diagram types
- Free and open source
- Large template library
- Real-time collaboration
Weaknesses:
- Steep learning curve
- Overkill for simple graphs
- No DOT language support
- Heavy on page load
Best for: Complex diagrams, architecture, wireframes.
Graphviz Charts for Confluence
What it does: Renders Graphviz DOT language directly in Confluence pages.
Strengths:
- Native DOT language support
- Lightweight, fast rendering
- Auto-layout algorithms (hierarchical, circular, random)
- 12 built-in shapes
- Inline in page content (no iframe)
Weaknesses:
- Requires DOT language knowledge
- No visual editor
- New app (no install history)
Best for: Org charts, dependency graphs, flowcharts, network diagrams — especially if you already use DOT language or want auto-layout.
Mermaid Plus for Confluence
What it does: Renders Mermaid diagrams (flowcharts, sequence, class, etc.).
Strengths:
- 29 diagram types
- Text-based syntax (like Graphviz)
- Live preview
- One-click templates
Weaknesses:
- Different syntax than Graphviz
- No DOT language support
- Some diagram types require specific Mermaid version
Best for: Flowcharts, sequence diagrams, Gantt charts — if you prefer Mermaid syntax.
Gliffy Diagrams
What it does: Drag-and-drop diagramming tool.
Strengths:
- Visual editor
- Good template library
- Enterprise features
Weaknesses:
- Paid only (no free tier)
- Slower than text-based tools
- No code-based diagrams
Best for: Teams that prefer visual editing over code.
Lucidchart
What it does: Cloud-based diagramming with Confluence integration.
Strengths:
- Real-time collaboration
- Extensive template library
- Enterprise security
Weaknesses:
- Expensive
- External tool (not native)
- Requires separate account
Best for: Large enterprises already using Lucidchart.
Head-to-Head: Graphviz Charts vs Alternatives
Graphviz Charts vs draw.io
| Criteria | Graphviz Charts | draw.io |
|---|---|---|
| Syntax | DOT language | Visual editor |
| Learning curve | Moderate (DOT) | Steep (features) |
| Performance | Fast | Slower |
| Best for | Code-based graphs | Visual diagrams |
Verdict: Use Graphviz Charts for auto-layout graphs. Use draw.io for complex visual diagrams.
Graphviz Charts vs Mermaid Plus
| Criteria | Graphviz Charts | Mermaid Plus |
|---|---|---|
| Syntax | DOT language | Mermaid syntax |
| Diagram types | Graph-focused | General-purpose |
| Auto-layout | Yes (4 algorithms) | Limited |
| Best for | Org charts, dependencies | Flowcharts, sequences |
Verdict: Use Graphviz Charts for structured graphs with auto-layout. Use Mermaid Plus for general-purpose diagrams.
Use Cases
| Use Case | Recommended App |
|---|---|
| Org chart | Graphviz Charts |
| Architecture diagram | draw.io |
| Flowchart | Mermaid Plus |
| Dependency graph | Graphviz Charts |
| Sequence diagram | Mermaid Plus |
| Network diagram | Graphviz Charts |

Quick Start: Graphviz Charts
- Install from Atlassian Marketplace
- Type
/graphvizin any Confluence page - Enter DOT language code:
digraph G {
A -> B -> C;
B -> D;
}
- Choose layout algorithm (dot, circo, fdp, random)
- Save the page — graph renders automatically
Frequently Asked Questions
Do I need to know DOT language? Yes. Graphviz Charts uses DOT language syntax. If you're new, start with simple graphs and expand.
Can I use a visual editor? No. Graphviz Charts is code-based. For visual editing, use draw.io or Gliffy.
What layout algorithms are available? dot (hierarchical), circo (circular), fdp (force-directed), random.
Can I export diagrams? Yes. Right-click the rendered graph to save as PNG or SVG.
Does it work with Confluence Cloud? Yes. Fully compatible with Confluence Cloud and Data Center.
