Build an AI-Powered Dashboard Generator Using Gemini Pro Vision and Python

What if you could automatically generate dashboards from your database using AI—with zero manual SQL or chart-building? In this post, I’ll walk you through building an AI-powered dashboard generator using Python, Plotly Dash, and Google’s Gemini Pro Vision model.

🧠 What We're Building
An interactive web app that connects to your database, analyzes your schema and data, and generates smart, AI-driven visualizations with explanations — no manual configuration needed.

🔍 Features
🔎 Automatic Schema & Data Analysis
Gemini detects column types, relationships, and sample data.

📊 Smart Visualization Suggestions
The AI recommends charts like bar, line, scatter, pie, and histogram based on data patterns.

🧠 Aggregations Made Easy
Auto-handling of sum, avg, count, min, max, grouped intelligently.

💅 Modern UI with Plotly Dash
Responsive layout, interactive graphs, real-time updates, and a smooth user experience.

📦 Technologies Used
Python 3.8+

Dash by Plotly

Google Generative AI SDK

SQLAlchemy (for database connections)

Gemini Pro Vision (gemini-1.5-flash or gemini-1.5-pro)

🔧 Setup Instructions

1. Clone the Repo & Install Requirements

git clone https://github.com/yourname/ai-dashboard-generator
cd ai-dashboard-generator
pip install -r requirements.txt

1. Create a .env File Add your database credentials and Gemini API key:

For SQLite

DB_TYPE=sqlite
DB_NAME=your_database.db
GOOGLE_API_KEY=your_gemini_api_key

PostgreSQL/MySQL config:

DB_TYPE=postgresql
DB_HOST=localhost
DB_PORT=5432
DB_NAME=your_database
DB_USER=your_username
DB_PASSWORD=your_password
GOOGLE_API_KEY=your_gemini_api_key

1. Run the App

python main.py

Then open your browser:
👉 http://localhost:8050

🔑 Getting a Gemini API Key (FREE)
Go to Google AI Studio

Sign in with your Google account

Click "Create API Key"

Copy and paste it into your .env

✅ Free Tier:
60 requests/minute, 1M characters/month, no credit card required.

📊 How It Works
Step 1: Schema Analysis
The app introspects your database using SQLAlchemy, identifying:

All tables

Column names & data types

Potential categorical/numeric/date fields

self.metadata.reflect(bind=self.engine)
self.inspector.get_columns(table_name)

Step 2: Prompt Gemini for Chart Suggestions
Gemini receives a structured prompt like:

Analyze this database table and suggest the best visualizations:
Table: users
Columns: ['id', 'age', 'signup_date']
...
It replies with JSON-like objects:

{
"type": "bar",
"x": "signup_date",
"y": "count",
"title": "User Signups Over Time",
"explanation": "Bar chart to show user signups grouped by date."
}
Step 3: Visualization with Plotly
The app uses plotly.express to build each visualization dynamically:

fig = px.bar(df_grouped, x='signup_date', y='count', title='User Signups Over Time')

You get interactive zooming, panning, tooltips, and more.

🖼️ Supported Visualizations
📊 Bar Charts

📈 Line Charts

🔵 Scatter Plots

🥧 Pie Charts

📉 Histograms

Each chart includes an explanation of why it was suggested — all powered by Gemini.

🧪 Demo Use Case

Imagine a sales table like this:

date    region  revenue
2024-01-01  East    1000
2024-01-02  West    850

The AI might generate:

A line chart: revenue over time

A bar chart: total revenue by region

A pie chart: revenue share by region

All of that, with zero manual chart coding.

🧠 Why Use Gemini?
Traditional BI tools require manual chart design. Gemini understands natural data patterns and recommends visualizations that:

Highlight trends

Aggregate meaningfully

Require no human SQL

It acts like a data analyst who just knows what to show.

🔓 License
MIT – free to use, modify, and build on.

📈 Future Ideas
Export charts to PNG/PDF

Embed dashboards in other apps

Natural language question support ("Show me revenue by month")

Row-level filtering

🌐 Conclusion
With just a Gemini API key and a database, you can now build AI-powered dashboards in minutes. Whether you're building for internal analytics, client reporting, or automating BI, this setup gives you insight on autopilot.
