Graph and Image Representations of Vulnerable and Non-Vulnerable Software Functions

The dataset contains image representations of source code files converted into three types of program graph-based views:
AST
PDG
CFG

The root directory includes three folders corresponding to these graph types:
dataset/
  ├── ast/
  ├── pdg/
  └── cfg/

Inside each graph-type folder, the images are categorized into two classes based on vulnerability status:
ast/
  ├── Vul/      # Vulnerable instances
  └── No-Vul/   # Non-vulnerable instances

pdg/
  ├── Vul/
  └── No-Vul/

cfg/
  ├── Vul/
  └── No-Vul/

The total number of images in each class across all graph types is:
No-Vul: 21,031 instances
Vul: 12,294 instances
All images are stored in .pkl format, where each file contains the serialized pixel data of a single graph image.
