Drupal taxonomy popular list

There are about 70 categories in Drupal 7 with taxonomy. I would like to get list 20 of the most popular(most used), sorted from most popular to the least placed in block.

Dogs (200 Entries)
Cats (120 Entries) 
..

Is there a module that has this functionality, or how would you get it开发者_运维百科 done.

You can use tagadelic module.

With a bit of CSS you can change the modules' display to not render popular tags larger then less popular tags.

And with a simple theme-override you can add the amount (200) of usage to the output too.
