I've used Confluence and SharePoint Wiki's in the past (Forgot what versions). With Confluence, the Wiki Markup Language allowed me to include a heatmap at the bottom of the wiki page to show the most popular topics / links users clicked on. Is there something similar in SharePoint 2013 Wiki WebPart?
I've done google searches, but only get 3rd party add-ons. I'm not seeing anything native in SharePoint 2013.
