We use only authoritative sources. We do not project, surmise or estimate in a graphic. We create work only from what we know. Except as authorized by a manager, we do not use graphics provided by others for which we lack the underlying data. We create charts at visually proper perspectives to give an accurate representation of data. The information must be clear and concise. We do not skew or alter data to fit a visual need. We credit our sources on every interactive and graphic, including graphics for which AP journalists have created the database.
