Visualization workflow - Template

This is a workflow template to collect customer and sales related data from different sources (local and remote) and different file types (Excel, CSV, database). The workflow should blend the collected pieces of data and do some data cleaning, transformation and aggregation to make it ready for visualization and further analysis. The last part of the workflow should build a composite view to visualize the data from different aspects.
The Microsoft Authentication and SharePoint Online Connector nodes are optional, all example files are bundled in the workflow's "data" folder and can be used via local file import.
