|
|
|
**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. |
