 ## 📌 Features
 
-- 🧠 **Unique Paths II (DP)**: Based on [LeetCode - Unique Paths II](https://leetcode.com/problems/unique-paths-ii/description/), visualize the total number of paths avoiding obstacles.
-- 📏 **Shortest Path Mode**: Visualize the shortest path between two draggable points using **Dijkstra's Algorithm** with 8-directional movement.
-- 📆 Animated step-by-step path traversal
-- 🧱 Click-and-drag to create obstacles on the grid
-- 🔄 Adjustable grid size (up to 12×12)
-- 👁️ Option to show/hide DP table values
-- 💡 Clear, responsive UI with Tailwind CSS
+- 🧠 **Unique Paths II (DP)**: Visualizes total valid paths using a dynamic programming table. Implements logic based on [LeetCode - Unique Paths II](https://leetcode.com/problems/unique-paths-ii/description/).
+- 📏 **Shortest Path Mode**: Uses a modified Dijkstra’s algorithm that supports 8-directional movement (diagonals included) for pathfinding.
+- 👡️ **Interactive Grid Editor**:
+  - Click or drag to add/remove obstacles.
+  - In shortest path mode, drag Start (🟩) and End (🟦) nodes freely.
+- 🧮 **DP Table Rendering**: Optionally display the number of ways to reach each cell in unique paths mode.
+- 🔁 **Path Animation**: Each cell in a computed path lights up sequentially to demonstrate traversal order.
+- 📀 **Resizable Grid**: Supports grids from 1×1 to 12×12 with smooth resets and state preservation.
+- ⚡ Fast and reactive UI thanks to React + Vite + Tailwind.
