# 🚗 Data Insights App

An AI-powered data analysis platform that allows users to explore a massive car auction dataset (558,000+ records) using natural language. The app combines **Streamlit** for the interface, **SQLite** for data management, and **OpenAI's GPT-4** for intelligent analysis and dynamic chart generation.

## 🌟 Key Features

### 🤖 Intelligent AI Agent
- **Natural Language Querying**: Ask questions like "What is the average price of a BMW?" or "Compare prices between California and Florida".
- **Dynamic Chart Generation**: Ask for visualizations (bar, line, pie, scatter) and the AI will generate them instantly.
- **Context-Aware Support**: If the agent can't help, it offers to create a GitHub support ticket with the chat history.

### 🛡️ Secure Data Management
- **ReadOnly Safety**: Strict SQL validation ensures only `SELECT` queries are executed. Dangerous operations (`DELETE`, `DROP`, `UPDATE`) are automatically blocked.
- **Privacy Guardrails**: The agent never communicates the full dataset, only relevant snippets (limited to 100 rows).

### 📊 Business Intelligence
- **Real-time Stats**: Instantly see total inventory, average prices, and price/year ranges in the sidebar.
- **Automated Insights**: Interactive top-make comparisons and condition distribution charts.
- **Console Monitoring**: A live developer console in the sidebar shows every action the AI and database are taking.
