Regression Line Grapher

This is a dedicated software for IB Physics Internal Assessments

Features

• General Polynomial Regression: Supports arbitrary positive and negative degree polynomials
• Multiple Regression Types: Linear, quadratic, cubic, inverse, inverse-squared, and more
• Interactive Frontend: Built with React/Vite for responsive data input and visualization
• RESTful API: FastAPI backend with comprehensive error handling
• Real-time Plotting: Dynamic chart generation with fitted curves

Supported Regression Models

• Positive Powers: y = aₙx^n + ... + a₁x + a₀ (standard polynomials)
• Negative Powers: y = a/x^n + b (inverse functions)
• Degree Range: -10 to +10 for numerical stability

Quick Start

1. Backend: cd backend && python -m uvicorn main:app --reload
2. Frontend: cd frontend && npm install && npm run dev
3. Access: Open http://localhost:5173 in your browser
