8 Useful JavaScript Libraries to Build Interactive Charts
Presentations often involve a lot of data which needs to be conveyed to clients. But making others understand raw data might be a tad bit difficult as not everyone has the same understanding of data. One of the easiest ways to deal with this problem is to make them understand data with the help of charts. JavaScript makes charts interesting by allowing users to add animations. With the help of JavaScript designers can now make charts interactive and playful. We’ve tried to gather some of the best JavaScript libraries to build interactive charts to make the job even easier for designers.
