Replicating User Journey Flow and Fallout Visuals in Power BI

Hello,

I have a Power BI Web Analytics Dashboard and I extract my data from Adobe Analytics using Report Builder and Datawarehouse. I am looking to explore ways of replicating Adobe Analytics visuals such as: user journey flow and fallout visual in Power BI. Do you have any ideas of how can I replicate these in Power BI, what data do I need to extract from Adobe Analytics?

I want to mention that I don’t want to use API or Raw Data Feeds as these require a higher level of effort and constant maintenance and my client does not want that. 

Is there any workaround? Or alternatives to understand how users navigate through the website? Any idea is welcomed.

Thank you,
