There are quite a few libraries for charts and visualization, there are not as many for actually combining many of them with layouts, different components and including the actual implementation of the backend. Dac aims to provide all that as a standard and an implementation.

I mean that's what the Vega team is doing no? They are building the standard grammar (Vega-Lite), along with an implementation (Vega). And they are already quite established with rich ecosystem, and supports a ton of components[0]. The only thing missing is that it expects a CSV or inline data source. But it's probably not too hard to build an extension that connects to a data warehouse with an SQL query.

I am not sure we are on the same page, as far as I am aware Vega doesn't do layout, does it? E.g DAC could use Vega for the charts and still take care of everything else around it.
