DrawPlus - Visual C++ Code Generator

A node-based visual programming tool that generates C++ source code. Create nodes representing C++ constructs (classes, functions, variables, loops, conditionals), connect them with typed links, and generate valid C++ code from the visual graph.

Features

• Visual node editor for designing C++ code structure
• Multiple node types: classes, functions, variables, loops, conditionals
• Typed pin connections (execution flow, data flow, booleans, integers, floats, strings)
• Real-time C++ code generation from graph traversal
• JSON save/load for graph persistence
• Configurable include headers
• Built with ImGui Node Editor for a responsive editing experience

How It Works

1. Create nodes representing C++ constructs from the context menu
2. Connect output pins to input pins to define data and execution flow
3. The tool traverses the graph and generates valid C++ source code
4. Save/load your visual graphs as JSON files
