Project Overview
The Advanced Mini Whiteboard is an interactive, web-based drawing application built using Django and HTML5 Canvas.
It allows users to draw, erase, adjust brush settings, zoom, collaborate in real-time, and save their artwork to a gallery.
This project focuses on delivering a smooth drawing experience with a clean and responsive UI — and it works without any external drawing APIs.
It serves as a strong example of combining Django backend, frontend canvas mechanics, and real-time WebSocket communication in one powerful mini project.
