[.sections[] | {
    page: .displayName,
    visuals: [ .visualContainers[].config | 
                                 fromjson |
                            .singleVisual | 
                select(has("projections"))|
    {
        type:.visualType,
        projections: .projections      | 
            {(keys[0]):[.[keys[0]][]   |
                           .queryRef   | 
 match("([^/(])[^/(/)]+(?=[/)])",".*") | 
                           .string
