About the activity overview
When you enable the activity overview section on your profile, viewers can see more information about the types of contributions you make and repositories you're most active in. A viewer can only see information in the activity overview about repositories they have read access to. Once enabled, a viewer can also filter your contribution graph and activity timeline for a specific organization. For more information, see "Viewing contributions on your profile."
