Iterate beyond the first output
Keep working through editing, refactoring, implementation details, and natural-language changes after the first generated result.
Source-code delivery
Generate complete graph visualization or graph editing apps that can be previewed online and downloaded as source code.

Graph application foundation
relation-graph is the graph interface foundation across DDJ's own products, from online diagram editing to AI-generated graph applications.

Build topology views, ownership maps, workflow diagrams, editable node-link applications, and other relationship-first interfaces.
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.
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.

Graph Online
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.
