 # Data Analyzer Agent
 
-AI-powered data analysis assistant using E2B Code Interpreter sandbox.
+AI-powered data analysis assistant that generates and executes Python code to analyze data and create visualizations.
+
+[![Live Demo](https://img.shields.io/badge/Live%20Demo-Try%20It-blue?style=for-the-badge&logo=huggingface)](https://davidleocadio94dlai-data-analyzer-agent.hf.space)
 
 ## Features
-- Generate Python code for data analysis
-- Create visualizations (matplotlib, seaborn)
-- Perform statistical analysis
-- Execute code securely in E2B sandbox
-
-## Setup
-Requires environment variables:
-- `OPENAI_API_KEY`: OpenAI API key for GPT-4
-- `E2B_API_KEY`: E2B API key for code execution sandbox
-
-## Usage
-1. Ask a data analysis question
-2. Agent generates and executes Python code
-3. View results and visualizations in chat
-
-Built with OpenAI GPT-4, E2B Code Interpreter, and Gradio.

+
+## Getting Started
+
+### Local Development
+
+```bash
+# Clone the repository
+git clone https://github.com/davidleocadio94/data-analyzer-agent.git
+cd data-analyzer-agent
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Set up environment variables
+export OPENAI_API_KEY=your-openai-key
+export E2B_API_KEY=your-e2b-key
+
+# Run the application
+python app.py
+```
+
+Visit `http://localhost:7860` to use the chat interface.
+
+## Example Queries
+
+Try these prompts to explore the agent's capabilities:
+
+- *"Generate 100 random numbers from a normal distribution and plot a histogram"*
+- *"Calculate the mean, median, and standard deviation of [23, 45, 67, 89, 12, 34, 56]"*
+- *"Create a scatter plot showing the relationship between x and y where y = 2x + noise"*
+- *"Analyze the correlation between two random variables and visualize it"*
