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

  1. Select a structure type.
  2. Build nodes and edges on canvas.
  3. Adjust node properties in inspector.
  4. 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.
