For 4 years now, the VIS4DH workshop has brought together researchers and practitioners from the fields of visualization and the humanities to discuss new research directions at the intersection of visualization and (digital) humanities research. The general aim is to foster productive collaborations that mutually advances all fields involved. Papers and invited talks from previous years can be found here. Re-Thinking Re-Defining Re-Imagining Data This year, we invite a dialogue on the topic and terminology around “data”, a contested term within and between a range of disciplines. There are varying perspectives on the meaning and use of data that impact how we engage and debate it. “Data” seems core to visualization! Or is it? We invite both theoretical and applied works at the intersection of visualization and (digital) humanities around these and other questions related to the workshop theme.
