Building a Real-Time Data Visualization Solution with Generative AI

Leveraging OpenAI, LangChain, and Streamlit for Intelligent Data Analysis and Visualization

This article demonstrates how to build a data visualization system that uses LangChain with LLMs to transform queries into interactive visual insights. The system integrates OpenAI’s GPT-4o-mini for query interpretation and data transformation, BigQuery as a data storage solution, and Streamlit to deliver real-time visualizations.

What We’re Building

We’ll create a full-stack data analysis system that:

• Converts text questions into optimized SQL queries
• Executes queries against BigQuery and processes results
• Extracts relevant data features (like coordinates for geographic data)
• Automatically detect appropriate visualization types based on query results
• Transforms data into format-specific visualization structures
• Provides real-time, interactive visualizations using Streamlit
• Explains insights into natural language
• Handles geographic data visualization with interactive maps and chart-based data visualization using…
