Two things I noticed:

1. In the add chart flow, the dataset in the dropdown isn't styled the same way as if you had selected the dataset manually
   

2. I think it would be smoother to bring the user directly to the create chart flow without the user seeing the dataset CRUD view in between, if we can do that. The dataset created confirmation toast could appear on the create chart page (instead of on the CRUD view)

cc @jess-dillard if you want to test on the ephemeral & for feedback on point 2

Agreed with @yousoph, let's make those changes.
