Konva.js is a powerful JavaScript library that helps you build interactive graphics applications on the web. Instead of working directly with the low-level HTML5 canvas API, Konva.js provides a higher-level way to create, manage, and interact with shapes and layers. This means you can focus on building features like dragging, resizing, and responding to user actions, rather than handling every pixel yourself.

Some of the main features of Konva.js include easy-to-use APIs for creating shapes such as rectangles, circles, and lines; support for grouping and layering, which lets you organize complex scenes; and built-in event handling, so you can respond to clicks, drags, and other user interactions. These features make it especially useful for applications like diagram tools, digital whiteboards, flowchart editors, and interactive presentations.

Unlike the native canvas API, which requires you to write code that draws everything manually and manages redraws, Konva.js handles much of this work for you. It lets you create objects, move them around, and listen for events in a way that feels more like working with HTML elements. This makes your code simpler, more organized, and easier to maintain as your application grows.
