Integrating Commercial chart library in Power BI without open sourcing it?

[mjaved]

You have created an open source framework "Power BI Visuals" , if any body want to integrate his custom charts in power BI, he has to develop the charts based on the standard set by this framework. Once any custom chart is added in this framework, it will be open source automatically. I have a custom charts library and i do not want to open source my library but still want to use my charts in Power BI, is there any option for that? what i want is , Only i should be able to use my charts in power BI dashboards that i create for my customers. no other developers or users should have access on my custom charts

Interesting feedback. To be clear: while the open source framework requires pull requests to be licensed under MIT, it does not mean you must open source your implementations. You can implement the IVisual interface in your own code. We will provide a way for you to upload your visual and use it within Power BI, though it's a little early to comment on how/when that would be enabled.
