ABSTRACT
Successful visual querying requires users to understand what data selection means and how it works in interactive and dynamically linked graphics. Visually selecting data differs from writing query or search statements, and users who are new to visualizations have to learn this new paradigm of querying. A usability study that I conducted provides findings about problems that users encounter in visual selection when analyzing data for a realistic, complex business problem. These problems reveal the program-based support that users need in order to make accurate, complete, and efficient selections. I identify combined improvements in user interfaces and Help that address these problems.
