Doubts regarding making the PowerBI dashboards

So I have made a few dashboards by downloading the gradient backgrounds from Pinterest and used it as background for dashboards. But, at the end of the day, I’m not using any other data visuals other than pie charts and bar charts. I tried a few kaggle datasets to explore things like Maps and Lists. But, I feel there’s so much more to learn.

I am currently looking out for Business Analyst jobs. So if someone can give suggestions to explore the PowerBI even more, it would be really helpful.

P.S. I tried using many YouTube videos but I need to more about PowerBI, so posting it here.
