VisCoder-7B is a large language model fine-tuned for Python visualization code generation and multi-turn self-correction. It is trained on VisCode-200K, a large-scale instruction-tuning dataset that integrates validated executable code, natural language instructions, and revision supervision from execution feedback.
π§ Model Description
VisCoder-7B is trained on VisCode-200K, a large-scale instruction-tuning dataset tailored for executable Python visualization tasks. It addresses a core challenge in data analysis: generating Python code that not only executes successfully but also produces semantically meaningful plots by aligning natural language instructions, data structures, and visual outputs.
We propose a self-debug evaluation protocol that simulates real-world developer workflows. In this setting, models are allowed to revise previously failed generations over multiple rounds with guidance from execution feedback.
π Main Results on PandasPlotBench
We evaluate VisCoder-7B on PandasPlotBench, which tests executable visualization code generation across three major libraries. Our benchmark covers both standard generation and multi-round self-debugging.
VisCoder-7B achieves over 90% execution pass rate on both Matplotlib and Seaborn under the self-debug setting, outperforming open-source baselines and approaching GPT-4o performance.
