Multi-Agent Visual Analytics Assistant with Preference Optimization

Upload tabular data (CSV / Excel / JSON), ask a question in natural language, and get an appropriate chart plus a grounded insight.

This is the single-agent baseline version. The multi-agent workflow, model comparison (prompt-only vs SFT vs DPO) and benchmark results are added in later project stages.

Note on latency: this Space runs Qwen2.5-3B on free CPU hardware, so the first response can take several minutes (the model also loads on first request).
