Welcome to DataWiz 2014, the 1st workshop on Data Visualization, one of the satellite events of the 25th ACM Hypertext conference, that is a premium venue for high quality peer-reviewed research on hypertext theory, systems and applications. DataWiz aims at bringing together an interdisciplinary audience (e.g. computer and cognitive scientists, designers, data journalists), in order to discuss tools, models and metaphors useful to understand and explain input or output data through advanced graphical user interfaces. In fact, interacting with data by means of intriguing visual representations, that can eventually be accessed from the Web, is a fundamental approach to accurately present scientific findings in an appealing way. The aim is to leave to the observer (likely an expert of the domain) the task of exploring complex phenomena, without the pain of dealing with issues such as data complexity and overload of information. This workshop focuses on both scientific and information visualization, with the aim of discussing of best practices and innovative approaches. 12 papers out 17 submissions were accepted for 20 minutes presentations; the morning session will open with the invited speech of Everardo Reyes-Garcia, whose contribution is included in the proceedings as well. All papers were initially assigned to be reviewed by three members of the PC. Final decision on borderline papers was made on meta-reviews written by the PC chairs. Thanks to their effort, the program includes lots of exciting ideas that we can't wait to share with you in our full-day workshop that will be held in Santiago, on September 1st. We thank all participants of the workshop for their contributions and the organizers of the Hypertext 2014 conference for their support. We hope that you will find this program interesting and thought-provoking and that the workshop will provide you with a valuable opportunity to share ideas with other researchers and practitioners from institutions around the world. We are looking forward to a very exciting and interesting workshop.
