C3.js

What it is

C3.js is a powerful and customizable JavaScript library built on top of D3.js, designed to simplify the process of creating interactive charts and visualizations. It provides a straightforward API that makes it easier for developers to integrate rich graphical representations into their web applications without deep knowledge of D3.js.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited customization options beyond default settings

   While C3.js provides extensive options for styling and interactivity, deeply customizing the charts to fit specific design requirements can be challenging due to its abstraction layer over D3.js.

2. 02

   Performance issues with large datasets

   C3.js may experience performance degradation when handling very large datasets, as it is built on top of D3.js which can be computationally expensive for complex visualizations.

3. 03

   Outdated documentation and examples

   The official C3.js documentation may not always reflect the latest features or best practices, leading to confusion and difficulties in implementing new functionalities.

What it does well

• Simplified API for D3.js-based charting

• Supports various types of charts including line, bar, pie, and scatter plots

• Highly customizable with extensive options for styling and interactivity
