What was the major new development in visualization in the past 10 years?

I don’t think there has really been one in decades. We’ve gotten better tools for making viz interactive but that’s about it.

You are probably right. I would not discount the importance of many open source tools for making viz more widely available (and far more powerful than excel graphs) but its indeed tooling, not conceptual and in any case already available for more than a decade. Stagnation indeed.
