About

DataVision turns raw CSV files into real‑time, AI‑powered business insights.
An agentic backend—built with LangGraph and powered by Gemini API—cleans data, runs hypothesis tests, and streams p‑values & richly‑styled visuals to a responsive frontend, giving small‑business owners clarity without complexity.

Features

Automated Pipeline: clean → design procedure → hypothesis testing → summarize. Statistical Insight:

• pandas handles data wrangling and feature extraction.
• SciPy selects and runs the most appropriate hypothesis tests.
• Instant Visuals:
  • Matplotlib & Seaborn generate publication‑quality plots (trends, distributions, correlations).
  • All charts are serialized as SVG/PNG and streamed to the UI for immediate rendering.
• AI‑Driven Exploration: Gemini‑powered chat lets users request custom analyses or deeper dives into their data.
• Real‑Time UX: UX is snappy, intuitive, and responsive.
