About Data Structure Builder
This tool visually builds common data structures (tree, graph, array, linked list, stack, queue) with node editing, connections, templates, and multi-language code export.
Key Features
- Structure Switcher: Tree/graph/array/linked-list/stack/queue modes.
- Node Operations: Add/remove/connect nodes and edit label/color/size.
- Canvas Editing: Visual graph editing for relationship understanding.
- Template Presets: Binary tree, graph example, and linked-list starter templates.
- Code Export: JavaScript, Python, Java, and C++ output.
Steps
- Select a structure type.
- Build nodes and edges on canvas.
- Adjust node properties in inspector.
- Choose output language and copy/export code.
Use Cases
- Data-structure learning and visualization.
- Interview explanation with quick diagram + scaffold code.
- Teaching/demo material preparation.
FAQ
Why do connections and output code look inconsistent?
Check selected structure mode and edge direction/selection sequence.
Is generated code production-ready?
It is mainly a structure scaffold; traversal and business logic should be added manually.
