PhonePe Pulse Data Visualization and Exploration: A Complete Project Walkthrough

By on


 Introduction

Imagine having the power to unveil hidden patterns in fintech data with just a few clicks. In the ever-evolving world of digital payments, understanding transaction trends and regional metrics can unlock transformative insights. That's exactly what I set out to achieve with my PhonePe Pulse Data Visualization project. By harnessing the capabilities of Python, MySQL, Streamlit, and Plotly, I created an interactive tool that not only simplifies data exploration but also reveals intriguing patterns in the PhonePe Pulse data. Join me as I walk you through this project that turns raw data into actionable insights and visually engaging stories.

Project Objective

The main objective of this project was to create a Streamlit application that enables users to:

  • Access and visualize PhonePe Pulse data interactively.
  • Store the data in a MySQL database for efficient querying and retrieval.
  • Display geographical insights using Plotly's geo-visualization features.
  • Offer multiple dropdown options for users to select and view different metrics and visualizations.

The project's aim was to provide a tool that simplifies the exploration of fintech data and offers valuable insights into transaction patterns and regional performance.

Approach and Implementation

To achieve the project objectives, I followed a structured approach involving six key steps:

  1. Data Extraction: Clone the PhonePe Pulse GitHub repository and extract data into a manageable format such as CSV or JSON.

  2. Data Transformation: Use Python and Pandas to clean and preprocess the data, ensuring it is in a format suitable for analysis.

  3. Database Insertion: Employ the mysql-connector-python library to insert the cleaned data into a MySQL database for efficient storage and retrieval.

  4. Dashboard Creation: Utilize Streamlit and Plotly to create an interactive and visually appealing dashboard. Plotly’s geo map functions display data geographically, while Streamlit provides a user-friendly interface with various dropdown options.

  5. Data Retrieval: Fetch data from the MySQL database into a Pandas dataframe and update the dashboard dynamically based on user selections.

  6. Deployment: Ensure the solution is secure, efficient, and accessible. Test thoroughly and deploy the dashboard for public access.

Technical Walkthrough

Let’s dive deeper into each step of the technical implementation:

  • Setting up the Streamlit app: I started by creating a basic Streamlit application. This interface allows users to select metrics from dropdown menus and view detailed geographical visualizations.

  • Connecting to the PhonePe Pulse data: I cloned the PhonePe Pulse repository and used Python to handle data extraction. The data was then cleaned and preprocessed using Pandas.

  • Storing Data in MySQL: The cleaned data was inserted into a MySQL database using mysql-connector-python. This setup ensures efficient data management and retrieval.

  • Creating the Dashboard: With Streamlit and Plotly, I developed a dashboard that provides interactive visualizations. Users can select different metrics and see data displayed on a geo map, helping them explore transaction patterns and regional insights.

  • Dynamic Data Updates: The dashboard updates dynamically based on user inputs, reflecting the latest data stored in the MySQL database.

Results and Analysis

The result of this project was a fully functional Streamlit application that offers:

  • Interactive Visualizations: Users can explore various metrics through an engaging interface.
  • Geographical Insights: Plotly’s geo maps provide a visual representation of transaction data across different regions.
  • Dynamic Data Updates: The dashboard reflects real-time changes, making it a valuable tool for ongoing analysis

Key Takeaways

This project was a fantastic learning experience, offering several key insights:

  • Data Integration: Learned how to integrate data from GitHub, preprocess it, and store it in MySQL.
  • Dashboard Development: Gained experience with Streamlit and Plotly for creating interactive and visually appealing dashboards.
  • Database Management: Improved skills in using MySQL for data storage and retrieval.

Future improvements could include adding more advanced interactive features, expanding data sources, and enhancing the dashboard’s visualization capabilities.

Conclusion

This project demonstrates the power of combining Python, Streamlit, and Plotly to create a robust tool for fintech data visualization. By leveraging these technologies, I was able to develop a dynamic and user-friendly dashboard that provides valuable insights into PhonePe Pulse data.
