Google mentioned on Google+ on the Google Analytics account, that a new AdWords reporting feature named Treemaps is coming to the software.

Treemaps promises to offer AdWords advertisers quicker insights into the performance of their ads. Google said these Treemaps will enable you to “visually identify trends and trouble spots across your account with speed and insight that you don’t have when looking at numbers alone.” They do this by displaying “hierarchical data using nested rectangles, showing positive results in green, and lagging results in red, speeding up your decision process,” Google added.

The feature should be live in the coming weeks and you’ll be able to see it under your Google Analytics account in Acquisition > AdWords > Treemaps.
