Your filter pane title already indicates that this is where a user filters the content. You don't need to call every slicer "Filter by.....". A small thing
Only other comment would be regarding the map. Personally I'm of the opinion that maps should only be used for geodata that is best represented in map form. Yours does not fit that bill, it's a qty by location in bubble fo4m and you would provide more insight with an alternative visual. Again, this is just a personal thing I have regarding the use of maps so feel free to ignore.
To offer an alternative, I'd be looking at a table visual, with attrition total, some time intelligence (Qtr, Yr, PY etc), maybe %share of the total and kpi indicators or sparklines to show trends.
