There is a sorting capability in Branch that allows you to sort by "most popular", this appears to translate to the number of views that an item has had. You might interpret this as relating to the most downloaded but it wouldn't be reliable. I have used several and quite like the google map, D3 Sankey and Word Cloud extensions among others.
Okay thank you for your sharing. I have bad experience in trying to using Map 6 year ago when i start with QV , a lot of headache. will try again since QS is more power full now.
