You can think of GraphicsJS as a paintbox with a brush, GraphicsJS may be used for data visualization, charting, game design or else. AnyChart charting libraries rendering is based fully on it.
GraphicsJS has one the most powerful line drawing features among SVG/VML based graphics libraries that provide only Bezier curves out of the box. But GraphicsJS is great at working with mathematical functions. As a result, GraphicsJS allows you to draw not only Bezier curves out of the box, but literally anything; for example, you can draw some arc very quickly, whereas other graphics libraries will make you arrange it through numerous different curves. And surely there are basic shapes available
GraphicsJS has implements the Virtual DOM which makes drawing more robust and manageable.
GraphicsJS uses smart layering system for elements and layers.
GraphicsJS supports z-index. Typically, if you ever decided to change the overlapping order, you would have to erase everything and draw the whole picture again, from scratch. With GraphicsJS, you are given the power to arrange this dynamically, which is extremely helpful when you are creating some big graphical thing and it is important for you to specify which elements must be seen at one moment or another.
GraphicsJS provides a convenient Transformations API that allows to move, scale, rotate and shear both elements and groups of elements. Transformations, in good hands, when used along with flexible Event Model and Virtual DOM, is a very powerfull tool.
GraphicsJS supports legacy browsers including IE6+.
GraphicsJS API is very convenient to use. Our API is very concise and provides chaining support, which makes it possible to use a dozen lines of code where other libraries require a hundred.
GraphicsJS is built on a very reliable technology, Google Closure, just like Google Mail, Google Calendar, Google Drive, and so on.
We recommend everyone to start with:
- Basics article lays out a general idea of the library and explains how things work.
- Paths, Shapes, Text and Fonts are the articles on drawing primitives, of which everything consists of.
- Layers article explains how the basic elements may be grouped and arranged.
- Transformations article explains how you can change elements and groups.
- Events article describes GraphicsJS event model.
