+# VisCoder2-7B
+
+[🏠 Project Page](https://tiger-ai-lab.github.io/VisCoder2) | [📖 Paper](https://arxiv.org/abs/2510.23642) | [💻 GitHub](https://github.com/TIGER-AI-Lab/VisCoder2) | [🤗 VisCode2](https://hf.co/collections/TIGER-Lab/viscoder2) 
+
+**VisCoder2-7B** is a lightweight multi-language visualization coding model trained for **executable code generation, rendering, and iterative self-debugging**.  
+
+---
+
+## 🧠 Model Description
+
+**VisCoder2-7B** is trained on the **VisCode-Multi-679K** dataset, a large-scale instruction-tuning dataset for executable visualization tasks across **12 programming language**. It addresses a core challenge in multi-language visualization: generating code that not only executes successfully but also produces semantically consistent visual outputs by aligning natural-language instructions and rendering results.
+
+---
+
+## 📊 Main Results on VisPlotBench
+
+We evaluate VisCoder2-7B on [**VisPlotBench**](https://huggingface.co/datasets/TIGER-Lab/VisPlotBench), which includes 888 executable visualization tasks spanning 8 languages, supporting both standard generation and multi-turn self-debugging.

+
+> **VisCoder2-7B** shows consistent performance across multiple languages and achieves notable improvements under the multi-round self-debug setting.
