Hi Madhuka,
I’m not aware of any efforts in bridging different chart libraries. But my guess is, we’ll have to do it ourselves. You can start by picking two different libraries or chart types and writing an implementation of the transformation function. It might help you to assess the scope of work. Regarding paragraph.js. I don’t think there is documentation for it. So the best way to understand the data flow it is to read the code. I know it’s not very helpful, but I don’t think anyone can help you in this situation.
