## Project Overview
This project analyzes the Colelithiasis dataset to perform exploratory data analysis (EDA) and prediction using pre-trained machine learning models. The goal is to provide insights into the data and make predictions efficiently.
## Objectives
- Perform EDA to uncover patterns and insights.
- Use pre-trained machine learning models for predictions.
- Create an interactive Streamlit application.
