What is the best alternative to Paper.js?

Because Processing doesn't keep track of shape objects it's more efficient than other libraries. Processing can do more complicated effects faster than other libraries. Although this means you have to keep track of more yourself in your code, it also means you have more control over the fi...

In processing you can write code in both JavaScript and Processing code. This allows you to use existing Processing code on the client side. Processing code is similar to Java in that it has static typing. This can make more complex calculations more robust, and less likely to cause conflicts. T...

Reference documentation and lots of examples are available directly on the website.

In few days any people can realice extremly complex figures in few minuts.

Besides having all consecrated charts like line, area, bar, horizontal bar, pie, bubble , it can have styles for line dots (solid dot, hollow dot, star, bow, anchor) or bar types (like dome, cylinder, parallelepiped). It has support for stacked bars, negative bars, combo bar-line charts, dual axis,

IE6+.

Clear and concise API with chaining support.

Rapid drawing. Only what is necessary is drawn.

Because Raphael supports rendering VML + SVG, it is one of the few drawing libraries that is backwards compatible with older browsers that do not support canvas.

Several built-in animations (such as ways of easing) are provided for you out of the box, but Raphael also allows cubic beziers for more complicated easing functions. Any drawing object property can be modified making it similar to css animations in jQuery.

Everything that is drawn in Raphael is an object which means it is easy to manipulate any part of the rendered image after it is processed. It uses an event handler system for user inputs which makes it easy to learn for JavaScript developers used to event based libraries. An interactive chart de...

Pixi is a WebGL renderer, but can fall back to canvas if WebGL is not supported or turned off.

Pixi.js uses a code structure that's very similar to ActionScript.

Dmitry Baranovskiy also wrote Raphael (project now owned by Sencha), this is the updated modern version of that library. Dmitry also is a champion directly affecting the future of SVG standards with W3C

Adobe is backing the development of snap.svg

Supports the newest SVG features like masking, clipping, patterns, full gradients, groups, and more

Fabric supports node.js, and has an npm package available for server side rendering with all the dependencies handled for you. This allows you to provide graceful degradation for image fallbacks to canvas or SVG content.

When it comes to format compatibility, Fabric is the best, with the ability to output to Canvas, SVG, and JSON. SVG provides backwards compatibility for older browsers, and JSON allows you to store rendered output for later use.

Drawing objects in fabric are vector focused, so everything is easily transformable. It makes it easy to create complex pathed shapes, add gradients, or filters. Although fabric is great for vector rendering, it also has image support as well.

Most of the examples provided are by the author, but there's also a great community writing plugins and more examples.

D3.js is a very popular tool with an active community, resulting in plenty of learning resources and fast responses to questions.

D3's emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework.

GFX can use a variety of formats to render (SVG, VML, canvas and SIlverlight). It simply does not lock you into one single browser's implementation of vector graphics.

3 APIs of increasing abstraction: Low-level (svg paths) Basic shapes (Polygon, Rectangle, Bezier, Sector, Connector etc..) Basic graphs (Pie, bar, stock, radar, tree, waterfall, sankey etc...) There is no magic, you can have as much control as you want on how you define your graphs, s...

Can be used together with a template engine such as Mustache or Handlebars to display SVG graphics or instead of a static template engine, you can use a data binding or MVC/MV* library, such as Ractive.js, Angular, Mithril or Facebook React.

Uses "the same api to draw in multiple contexts: svg, canvas, and webgl."

Good examples.

Pergola runs seamlessly in an HTML environment (option in configuration file). All the examples are provided both as SVG standalone and embedded in HTML, and are strictly equal. Besides its universal Node Helper (http://www.svgmagazine.com/jul2011/dom-helper.html) Pergola also provides the equiva...

The first and most accomplished SVG native library, 100% cross-platform compatible.

It's one of the easiest drawing libraries to learn.

Each chart can be implemented to ASP.NET and ASP.NET MVC applications, with detailed documentation and guides for each.

There are more than 20 types of charts available for use.

Each of the available charts has documentation and guides available for every different implementation (JavaScript, ASP.NET etc.)

Three.js offers a canvas renderer as a fallback when WebGL is not available.

The documentation is detailed, providing clear explanations and code samples of the various features. There are also hundreds of examples available.
