Data visualization has the potential to change the questions that people are able to pose to their data and transform their analytical methods and decision-making processes. It may, in fact, be the next generation of data reporting tools. This article argues that the prevailing computer science orientation to data visualizations is severely limited for addressing many of the usability concerns associated with supporting users in three critical problem areas: sophisticated visual literacy, complex data analysis, and new paradigms of visual inquiry. I first describe what visualization technology is and what is uncharted about the three usability areas of perceptually rich, interactive displays; complex problem-solving; and visual querying. Then I explain what it means to take a computing -- specifically an object-oriented -- perspective on the usability of visualizations, emphasizing the limitations of this point of view when it comes to supporting users in complex activities and reasoning.
