Implement a visualizer for current ICA analyzer (d3.js/svg)

It would be nice to display the results of ICA as spatial maps, i.e.
displaying the weights of a certain component over the brain surface

I imagine it could adapt depending on the "source" TimeSeries:

• TimeSeriesRegion dtypes: - graph displays like the 2D Connectivity visualizers (the size/color of the nodes is given by the weights).
• when selecting a node the component time-series (scaled by the corresponding weight) is displayed.
• OR for a given component, display in a topology map its value for every region (applying some interpolation and smoothing) – see attached figure visualizer_ICA

• TimeSeriesSurface dtypes: - my guess is that in this case displaying the component loadings is not very relevant.
• displaying the surface (3D view as in Local Connectivity/Surface Stimulus) for a few components.

Issues:
..........

Selecting # first dominant components based on the non-normalized mixing matrix (L_

-norm?).

Need to add references and develop more
