For a good start to 2021, I have created my own custom visual for PowerBI which you can use as an option to Bar charts. You can use this chart to display different categories on X & Y Axis . Drilldown functionality works perfectly fine on the report.
Chart based on : http://graphics.wsj.com/infectious-diseases-and-vaccines/
Below is the snapshot of the Visual:
You can have a look at the visual on my website link here : https://www.sshadowfax.com/covid-dashboard >> Click on New Custom Visual button.
Do let me know if you need the PbiViz file for your learning.
PS: I will keep on updating the visual with new updates as I move along....
