An interactive Streamlit and Plotly dashboard that extracts, processes, and visualizes digital payments and user data from the PhonePe Pulse GitHub repository using MySQL and Python.

📊 PhonePe Pulse Data Visualization and Exploration

This project aims to extract, process, and visualize large-scale data related to digital transactions and user statistics from the PhonePe Pulse GitHub repository. The data is transformed and presented through an interactive and user-friendly web dashboard built using Streamlit and Plotly.

🚀 Project Overview

• 📁 The project was developed locally in VSCode, within a newly created virtual environment.
• 🔗 I cloned the PhonePe Pulse repository from the GitHub link provided by the GUVI team to extract and download the required dataset.
• 🛠️ A new database named phonepe_pulse.db was created, and the extracted data was structured into appropriate tables and inserted using custom scripts.
• 📊 A two-page Streamlit dashboard was designed and developed based on the core requirements of the project.
