(dataset data
         {:keys [single-value-column-name column-names layout dataset-name
                 stack-trace? error-column?]
          :or {single-value-column-name :$value
               layout :as-rows
               stack-trace? false
               error-column? true}

Create dataset.

Dataset can be created from:

• map of values and/or sequences
• sequence of maps
