Abstract

Our age has resolved critical actions in managerial processes such as storage and retention of data. Thishas created a huge pile of data waiting to be processed, making the processing and visualization of datavaluable as a way of making sense of and expressing it. Visualization provides a powerful representationto extract meaning and discover insights from data. This representation strengthens the narrative andenriches the story. Institutions and organizations often use visualization in their reports and presentationsto take advantage of this effective power. But this is not as easy a reference as it may seem. It is difficultto use and complex to implement. When not used correctly, it creates greater complexity and makes thestory to be told multi-layered. Therefore, visualization needs to be done in a way that is faithful to itscontext and appropriate for its target audience, taking into account the data to ink ratio. Within the scopeof this study, data visualization techniques used in the most recent annual reports of 39 districtmunicipalities of Istanbul published as open access were identified and classified. The types and featuresof the charts used were analyzed and the applications were examined. If universal principles are takeninto account, errors in preferred visualization formats and chart types have been identified. This studyis important in terms of examining and evaluating the visualization techniques in the annual reports ofpublic institutions.
