Konva is an object-oriented HTML5 canvas framework designed for building interactive 2D graphical applications. It provides a hierarchical scene graph that organizes shapes, images, and text into manageable nodes, groups, and layers. By mapping application state to canvas elements, the library enables developers to create complex visual interfaces using declarative patterns that synchronize with modern component-based frameworks. The library distinguishes itself through a robust event system that supports hit detection, bubbling, and direct manipulation of graphical objects, such as dragging,
