Hi Torbin, and welcome to the community!
Despite the benefits of a seamless integration with Tableau, one of the challenges for [any] vendor is to pick integration winners and back them with long-term commitments for comprehensive support of the feature set. This also applies to internal design choices such as the Charts Block.
But charting - in general - is a very slippery slope because no person or team can ever predict and develop the perfect charting tool. Tableau comes close, but a quick examination of their forum demonstrates that even the best in the business fall short in some ways. This is not uncommon in data visualization tools and it’s why I believe open-design choices are the best strategy.
The recent addition of Vega-Like is a good example of how data visualization integrations should emerge. But the most important aspect of this integration is that no one at Airtable had to contact anyone at Vega.
In my view, this is how good integrations should work; they should be able to emerge without collaboration because if deep conversations are required to pair any two systems, one or both of the vendors has failed to create a truly open architecture.
