An interactive visualization of the **classic “chessboard and rice grains” exponential growth problem**,  
built with **Gradio** and **Plotly**, and ready for deployment on **Hugging Face Spaces** 🚀

## 🎯 What It Does

- Visualizes how rice grains double on each chess square (1 → 64).  
- Interactive **chessboard heatmap** of grains (log scale).  
- **Exponential growth** and **cumulative total** line charts.  
- Real-world **comparisons** (vs. world population, sand grains, etc.).  
- Dynamic **stats panel** that updates as you move the slider.
