Zhe Cui, Sriram Karthik Badam, Adil Yal\c{c}in, Niklas Elmqvist

TL;DR
DataSite is a proactive visual analytics system that automates computation suggestions, turning data analysis into an interactive conversation to reduce cognitive load and improve complex data exploration.
Contribution
It introduces a system that combines automatic background computations with user notifications, enhancing data exploration efficiency and effectiveness.
Findings
Significantly improves analysis efficiency for complex tasks
Reduces cognitive load during data exploration
Outperforms recent visualization recommendation systems
Abstract
Effective data analysis ideally requires the analyst to have high expertise as well as high knowledge of the data. Even with such familiarity, manually pursuing all potential hypotheses and exploring all possible views is impractical. We present DataSite, a proactive visual analytics system where the burden of selecting and executing appropriate computations is shared by an automatic server-side computation engine. Salient features identified by these automatic background processes are surfaced as notifications in a feed timeline. DataSite effectively turns data analysis into a conversation between analyst and computer, thereby reducing the cognitive load and domain knowledge requirements. We validate the system with a user study comparing it to a recent visualization recommendation system, yielding significant improvement, particularly for complex analyses that existing analytics…
