# LLM Excel Plotter Agent

An intelligent Hugging Face Space that uses Large Language Models to process Excel data, generate meaningful charts, and provide automated analysis.

## Features

- 📈 **Intelligent Chart Generation**: Uses Qwen2.5 and BART models to understand data and generate appropriate visualizations
- 🤖 **LLM-Powered Analysis**: Leverages state-of-the-art language models for data interpretation
- 📊 **Multiple Chart Types**: Supports line charts, bar charts, scatter plots, and more
- 🎨 **Interactive UI**: Clean, modern interface built with React and Plotly.js
- 📁 **File Upload**: Process CSV files and get instant analysis

## Models & APIs

### Local Models (Free)
- **Qwen2.5-1.5B-Instruct**: Local inference for data analysis
- **BART Fine-tuned**: Custom model for structured text generation

### Supported External APIs (Optional)
- Gemini 2.0 Flash: Add `GEMINI_API_KEY` environment variable
- Grok-3 Mini: Add `GROK_API_KEY` environment variable

## Usage

1. Upload a CSV file containing your data
2. Ask the chatbot to analyze or visualize specific aspects
3. View generated charts and insights
4. Export results or ask follow-up questions

## Deployment

Built with:
- **Backend**: Flask (Python 3.10)
- **Frontend**: React 18.3.1
- **LLM Integration**: Transformers, HuggingFace Inference
- **Data Processing**: Pandas, Scikit-learn

Deploy to Hugging Face Spaces with Docker support enabled.

## Health And Wake-Up Endpoint

To support cold-start recovery on free-tier Hugging Face Spaces, this backend exposes:

- `GET /health`

This endpoint is lightweight and intended for:

- frontend wake-up checks before user requests,
- retry logic diagnostics,
- optional cron-based warm-up pings.

Example:

```bash
curl https://<your-space>.hf.space/health
```

Typical response:

```json
{
	"status": "ok",
	"service": "llm-excel-plotter-agent",
	"uptime_seconds": 12.34,
	"timestamp": 1700000000
}
```
