One of the things I like the most about Power BI is the ability to use custom visuals. I did not try building one myself and honestly I think it’s beyond my skills, yet there is a gallery with a growing number of pre-build viz that you can download and use.
Go to https://app.powerbi.com/visuals?WT.mc_id=Blog_Visuals and take a look.
I downloaded the WordCloud plus the Chiclet Slicer to create a report showing the trending topics in Twitter sliced by date and location.
Only few locations are available from Twitter API, here is a sample of spanish cities I am monitoring.
