📦 Installation

Install Vizify using pip:

pip install vizify

🚀 Usage

1. Import the Package

from vizify import Vizify

2. Generate a Basic Visualization Report

from vizify import Vizify

# Initialize Vizify with a CSV file
viz = Vizify("your_data.csv")
viz.show_all_visualizations()

After execution, a file named data_visualization_report.pdf will be created in your working directory containing all the visualizations.

3. Generate a Visualization Report with AI Interpretation

from vizify import Vizify

viz = Vizify("your_data.csv", api_key="YOUR_GEMINI_API_KEY")#Place your API KEY here
viz.show_all_visualizations()

4. Launch Interactive Dashboard (NEW)

Launch the dashboard directly from Python in just two lines:

from vizify import Vizify

Vizify.launch_dashboard()

Or use the command-line interface:

if __name__ == "__main__":
    # This will prompt you to choose between PDF report or interactive dashboard
    from vizify import main
    main()

5. Machine Learning Training (NEW)

🧠 ML Model Training via Interactive Dashboard

Vizify’s dashboard makes machine learning effortless. Just follow these steps:

1️⃣ Upload Your CSV File

Use the file uploader in the sidebar to load your dataset.

2️⃣ Enable ML Model Training

From the sidebar, check the "ML Model Training" option to activate the training wizard.

3️⃣ Follow the Step-by-Step Wizard

• Choose Problem Type:
  Select whether you're solving a Regression or Classification problem.

• Select Features and Target Variable:
  Pick the input features and the column you want to predict.

• Configure Preprocessing Options:
  Handle missing values, encode categorical variables, and scale features.

• Select Algorithms to Compare:
  Choose from multiple models like Linear/Logistic Regression, Random Forest, Decision Trees, SVM, and KNN.

• Train Models with One Click:
  Run training and view performance metrics instantly.

4️⃣ Download Trained Models

Export your best-performing model as a .pkl file for production use.

---

This flow turns Vizify into a no-code ML powerhouse—perfect for analysts, business users, and data scientists alike.

💬 Conversational AI Usage

Vizify now includes a powerful Chat with Data capability.

1️⃣ Global Chat

• Located in the Sidebar.
• Use this to ask general questions about your dataset (e.g., "What are the columns?", "Summarize the trends").

2️⃣ Per-Chart Chat

• Located below every chart you generate.
• Click the "💬 Chat about this chart" expander.
• Ask questions specific to that visualization (e.g., "Why is there a spike in 2023?", "What does this outlier represent?").
• The AI has access to the specific data subset used for that chart.

🤖 AI Settings

• Use the AI Settings dropdown in the sidebar to switch models if you encounter rate limits or want to try a different capability (e.g., gemini-2.0-flash).
