Add a "default." object that holds the default values to be fed into the widgets

Add a "control.*" object that holds the outputs of the widgets to be fed into the models.

Use a "model.*" object that holds DataFrames output from the Models rather than passing multiple pieces of related information (ei. s, i, and r vectors).

Feeded "control.* and "model." into the Charts, Have the Charts produce properties of a "view." object that can be unit tested. Usually a projection of a model or model(s) DataFrames.

Separate Chart render from the 'view.*' for unit testing.

Have a render that takes default, control, model and view objects
