DiagramGPT-Llama3: Enabling Editable, High-Fidelity Diagram Generation with Vision Large Language Models

The automation of diagram generation has gained significant attention in recent years. Previous studies mainly focused on generating diagrams from natural language, but often lacked support for user-friendly editing like drag-and-drop. This paper proposes a novel task: generating editable, high-fidelity diagrams from either text or raster images. It is also among the first to introduce diagram restoration and style transfer in this setting.To tackle these tasks, we constructed the Diagram-mxGraph dataset, covering restoration, text-to-diagram generation, and style transfer. We propose two core innovations: Fine-grained Adaptive Background Suppression (FABS) and Component-Aware Adaptive Loss (CAAL). Leveraging pre-trained Vision Transformers (ViTs) and the Diagram Adapter module, our method aligns diagram features with a Large Language Model (LLM) to output diagrams in editable mxGraph format.
