As promised, today we will continue working on our Presidential Word Cloud that we have started here, and will focus on two important and useful techniques which are not only relevant for Facebook analysis in Power BI:
- We will learn how to extract words from textual columns without splitting the column to many columns.
- By splitting messages to single words, our Word Cloud visual in Power BI will work better, we will be able to resize it, and drill down from a single word to its original message.
Oh, and the relation to Ghostbusters will be revealed at the end.
To recap our current challenge – In our last tutorial we have created a Word Cloud which is not resizable.
To fix this limitation, we will need to create a new column in our query for the individual words, and feed this column to the Word Cloud visual.
