C3.js vs T3: What are the differences?
C3.js: A D3-based reusable chart library. c3 is a D3-based reusable chart library that enables deeper integration of charts into web applications; T3: Client-side JavaScript framework for building large-scale web applications, created by Box. T3 is different than most JavaScript frameworks. It's meant to be a small piece of an overall architecture that allows you to build scalable client-side code. T3 is explicitly not an MVC framework. It's a framework that allows the creation of loosely-coupled components while letting you decide what other pieces you need for your web application. You can use T3 with other frameworks like Backbone or React, or you can use T3 by itself.
C3.js can be classified as a tool in the "Charting Libraries" category, while T3 is grouped under "Javascript UI Libraries".
C3.js and T3 are both open source tools. It seems that C3.js with 8.42K GitHub stars and 1.4K forks on GitHub has more adoption than T3 with 1.59K GitHub stars and 160 GitHub forks.
