Adapt Chart visualization for Dash/Kaleido

[kMutagene]

Description

Currently, The (single) GenericChart type is a tuple of data, layout, and config. Different endpoints such as the Dash Graph component or Kaleido that accept plotly graphs in JSON format however expect these to be fields of the same object, e.g.

{
    "data" : ... , 
    "layout": ..., 
    "config": ...
}

or at least

{
    "data" : ... , 
    "layout": ..., 
}

with the config object being separate

We should adapt the type accordingly, either by making both Union cases of GenericChart inherit from DynObj or abstracting Chart/MultiChart as record types. Additionally, we should adapt the html scaffold for displaying Charts to render plotly graphs directly from that Json instead of declaring data/layout/config objects in a script tag.

Reference docs from plotly.py specifies the top level fields of the figure object as data, layout, and frames. As frames is needed for animations, which are currently not supported by this library, the first step is supporting data and layout and omitting frames until animations are supported.

Converting the cahrt to the figure type (918adc2) is not perfect but will do for now.
