Hey, welcome back, here you will find all the data visualizations and stories i have created, they are mainly done in Power BI but you might find one or two on tableau,
Personally i'm a huge fan of clean designs, but, as you know that depends on the target audience, come take a look
To check my visuals --->Power Dashboards
I like to follow the guidelines from the book StoryTelling With Data, it's REALLY good, clean, simple and easy to follow.
