Virtualization with React.js

I am using the GoJS ReactDiagram and with larger data sets the load time is getting slow.
Are there any examples of virtualization with the ReactDiagram component?

Sorry, I am not able to find any samples with that combination of features that you ask about.

My opinion is that a design using immutable data is going to be slower (less responsive, use more memory) than a design that permits modifying data, which is how GoJS was designed.
