This is the historical approach. • License: The author(s) retain copyright, but ACM receives an exclusive publication license. • Open Access: The author(s) wish to pay for the work to be open access. The additional fee must be paid to ACM. This text field is large enough to hold the appropriate release statement assuming it is single spaced. Abstract Adaptive visualization has the potential to improve the accessibility of information in personal informatics systems while reducing the effort required of developers and designers to target data visualizations to specific use cases and specific users. Users have many widely differing needs, and they vary equally in their ability to understand visualizations. That ability is based on individual differences in personality and circumstances among others. We aim to demonstrate that adaptive visualization is a viable direction for designing personalized visualizations, and that it has benefits for both users, designers and developers. We present issues in personalized visualization, how adaptive visualization may be used to address them, and our view for moving a research agenda forward in this domain.
