C3.js vs Charted: What are the differences?

Developers describe C3.js as "A D3-based reusable chart library". c3 is a D3-based reusable chart library that enables deeper integration of charts into web applications. On the other hand, Charted is detailed as "A charting tool that produces automatic, shareable charts from any data file". Charted is a tool for automatically visualizing data, created by the Product Science team at Medium. Provide the link to a data file and Charted returns a beautiful, interactive, and shareable chart of the data.

C3.js and Charted can be categorized as "Charting Libraries" tools.

Some of the features offered by C3.js are:

• Comfortable - C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more.
• Customizable - C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3.
• Controllable - C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even if after it's rendered.

On the other hand, Charted provides the following key features:

• Rendering well on all screen sizes, including monitors
• Re-fetching the data and updating the chart every 30 minutes
• Moving data series into separate charts

C3.js and Charted 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 Charted with 2.73K GitHub stars and 193 GitHub forks.
