Abstract: A data analytics application receives a workflow that includes a sequence of tools. Each tool in the sequence performs a data analytics function. The data analytics application generates an interactive element for a tool in the sequence based on the data analytics function of the tool in the workflow. The interactive element is applied to the tool to update the workflow. The interactive element may be affiliated to the tool or be added into the analytics workflow as a new tool. The updated workflow is provided for processing a data file. The updated analytics workflow generates a result item representing an outcome of the processing of the data file. The interactive element applied to the tool is adapted to receive a user input and to trigger an operation of the tool based on the user input to generate a different result item.

Abstract: A server has a data processing module with instructions executed by a processor to maintain a collection of visualization frames that characterize a sequence of data analytics. Each visualization frame is a snapshot of data and the collection of visualization frames has associated permissions and visualization settings. A user navigation path through the collection of visualization frames is maintained. The navigation path specifies a data set used and a dimension accessed in the data set. A recommendation for a new visualization based upon the user navigation path is supplied. A new visualization selection is accepted and a new visualization is rendered based upon the new visualization selection.
