The Web Part, “Org Chart”, that was visible under the About Me section of MySites in previous versions of SharePoint is now hidden in SharePoint 2013 by default. But when you view the About Me page of any another employee it is displayed. This behavior is by design and it’s for better performance reasons.
In previous versions of SharePoint, the profile page always loaded the Org Chart web part. Loading peer, manager and direct report data actually requires an extra database lookup which contributes to a longer page load time. Since most users would prefer to have their personal profile page load faster than to see their own position in the organizational hierarchy, the Org Chart web part is hidden when a user views their own profile page.
