JavaScript InfoVis Toolkit vs. Preact vs. RequireJS vs. Synfig Studio Comparison Chart

Preact provides the thinnest possible Virtual DOM abstraction on top of the DOM. It builds on stable platform features, registers real event handlers and plays nicely with other libraries. Most UI frameworks are large enough to be the majority of an app's JavaScript size. Preact is different: it's small enough that your code is the largest part of your application. That means less JavaScript to download, parse and execute - leaving more time for your code, so you can build an experience you define without fighting to keep a framework under control. Preact is fast, and not just because of its size. It's one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation. We automatically batch updates and tune Preact to the extreme when it comes to performance. We work closely with browser engineers to get the maximum performance possible out of Preact.

Synfig Studio is a free and open-source 2D animation software, designed as a powerful industrial-strength solution for creating film-quality animation using a vector and bitmap artwork. It eliminates the need to create frame-by-frame animation, allowing you to produce 2D animation of a higher quality with fewer people and resources. Transform any vector shape into another! Synfig gives you powerful tools for full control of your vector artwork. Just set the key positions and the intermediate frames will be calculated automatically. Synfig provides more than 50 layers to create illustrations and animations of any complexity. Choose from several types of layers: geometry, gradients, filters, distortions, transformations, fractals and others. The full-featured bone system allows you to create cutout animations using bitmap images or control your vector artwork.
