I published this dashboard on Tableau Dashboard as an example of Exploratory Analysis based on Movie DB Data https://public.tableau.com/profile/fabioitaliano#!/vizhome/TheMovieDB/DataStorytellingExample It includes a Storytelling Example and interactive examples on Industry Trends, Novels vs Other Genera, and Profitability of Directors (see below) The intent here is to show that data exploration is as much part as machine learning in the Data Democratization process. Enabling a wide business audience to run this type of analysis with connected Data Lakes (with Knowledge Graphs), and self-service analytics tools,  is an essential value creation component.
