Is your feature request related to a problem? Please describe.
In summary view, the Wheeler diagram is split in two parts, describing dominant facies and sedimentation rate separately. As a result, the x axes do not match those of the profile plot, making it difficult to intuitively associate positions between the plots. It would be nice to be able to allow users to have more control over the type of Wheeler diagram shown.

Describe the solution you'd like
Export both dominant_facies! and sediment_accumulation! for the Visualization extension so users can build their own Wheeler diagram if they wish to without having to resort chunks of code from the documentation.

Describe alternatives you've considered
Copy the plotting code from the documentation into scripts that assemble the plot - not an elegant or sustainable solution.
