relation-graph
MIT graph SDK for visualizing and editing relationship data across Vue, React, Svelte, Web Components, and native HTML.
Focused on Data Intelligence
Complex data, clearer relationships
DDJ Intelligence, LLC operates three connected product lines: relation-graph provides the open-source graph foundation, Graph Online turns natural-language intent into editable relationship diagrams, and RG GraphPilot generates runnable graph applications with source code. DDJ.ai is also available for scoped data analysis and visualization service discussions.
Complex data analysisRelationship visualizationNatural-language diagram generationGraph application generationSoftware-assisted reporting
RG GraphPilot
Turn graph requirements into runnable visualization or graph-editing applications with online preview and downloadable source code.
Graph Online
Generate editable relationship diagrams from natural language, then refine data, layout, and styles in the editor.
What is RG GraphPilot?
RG GraphPilot is a specialist graph-application agent for real delivery. It does not stop at drawing a graph once. It keeps working through editing, refactoring, implementation, and continuous natural-language iteration.
Online graph app development agent
RG GraphPilot
Each GraphPilot call can build a complete runnable graph visualization or graph editing app with online preview and full source-code download.
Build from your requirement
Describe your data, interactions, and business goal to build the graph application you need.
Modify site examples
Modify any example already published on this site, within the example range available to your current membership level.
Migrate your current graph app
Support migration or modification based on your current graph application. Even non-relation-graph stacks are supported, but the result will be rewritten into a relation-graph implementation.

RG GraphPilot
A graph-drawing agent built on the RG Graph Expert Knowledge Base and hundreds of relation-graph scenario patterns. It generates graph application code that remains AI-iterable, can interact with your own system code, and supports every frontend stack; RG GraphPilot better understands scenarios, data, and algorithms.
- Outputs code that can continue to be understood, edited, and iterated by AI
- Can interact with and integrate into your existing system code
- Supports Vue 2, Vue 3, React, Svelte, and native HTML stacks
- Understands scenarios: can choose the most suitable viewing or editing approach from the needs and data you describe
- Understands algorithms: is fluent in dozens of professional graph layout and graph operation algorithms, including center, force, multiple tree layouts, workflow, area-based layouts, shortest path, data flow routing, grouping, undo and redo, and drag-to-create links
Focused on graph apps, not generic AI noise
RG GraphPilot is a specialist agent for graph visualization and graph editing, with clear scope and delivery-oriented outputs.
- RG GraphPilot is not an all-purpose AI tool. It is an agent focused on concrete graph-visualization and graph-editing problems.
- Its core job is writing code and helping you build interactive code that can keep evolving.
- It is charged by credit consumption, so you do not carry a subscription burden.
Core open-source product
relation-graph: the graph SDK behind AI-ready graph applications
relation-graph combines an MIT-licensed graph SDK with mature examples, documentation, and architecture for relationship-heavy applications. It is designed for both graph display and truly interactive graph editing.

Display + Edit
Graph application foundation
It serves as the graph interface foundation across DDJ's own products, from online diagram editing to AI-generated graph applications.
LLM-friendly graph scenariosSSR and cross-platform consistencyEnterprise-ready delivery path
Display and editing
One SDK for graph views and graph editors
Build topology views, ownership maps, workflow diagrams, editable node-link applications, and other relationship-first interfaces.
Multi-framework
Consistent concepts across frontend stacks
Use native implementations for Vue, React, Svelte, Web Components, and HTML while keeping visual, data, interaction, and architecture concepts aligned.
AI-ready
A practical foundation for LLM workflows
Structured data, examples, and repeatable graph concepts make relation-graph suitable for knowledge-base integration and AI-assisted graph delivery.
Engineering assets
Docs and examples for real implementation
Rich examples and documentation reduce learning cost and give teams reference paths for complex graph application work.
Online product
Graph Online: natural-language relationship diagram workspace
Graph Online turns natural-language requests into editable relationship diagrams. After generation, users can keep editing the data model, layout, labels, colors, and line styles directly in the editor.
Generate editable diagrams
Describe entities, relationships, and intent in natural language, then receive a graph diagram that can be opened and edited immediately.
Refine data and style in the editor
Adjust nodes, links, groups, labels, layout, colors, and line styles without leaving the browser workspace.
Define complex custom nodes by prompt
Use natural language to describe rich node components, such as KPI cards, status badges, nested fields, or domain-specific visual states.
PROMPT > "Generate an editable supplier-risk relationship diagram from this description."
GRAPH ONLINE > Creates nodes, links, groups, labels, and starting styles.
EDITOR > Refine data fields, layout, colors, labels, and line styles.
CUSTOM NODE > "Use a KPI card node with risk score, owner, and status badge."
