Abstract

In written and spoken communications, metaphors are often used as an aid to help convey abstract or less tangibleconcepts. However, the benefits of using visual metaphors in visualization have so far been inconclusive. In this work, we reportan empirical study to evaluate hypotheses that visual meta...
