Graphs in MS Teams / MS Planner

Hello,

I have created a team with 8 members and 10 channels in it, in each channel there are about 20 tasks and number is growing. I can easily display progress in graphs for individual channels, but I don't see any possibility to get graph from all channels, ie a general overview of the status of my team's tasks.
Is there this option (for example, creating an application in Power Apps or using Power BI)?

Thanks
