It’s tempting for those who work with numbers and spreadsheets, for those who live by the bottom line and whose minds run along quantitative paths to think that art exists for its own sake. It’s tempting to think of art as something nice for the wall, pleasant to look at, maybe even restorative or inspiring in its impact, but ultimately not essential to the running of the world.
Yet consider the work of University of Maryland Computer Science Prof. Ben Shneiderman. Shneiderman is the inventor of treemaps — those graphics that chart often vast quantities of hierarchical data, such as electronic health records. He’s also famous for the eponymous “Shneiderman’s Mantra” of visual data analysis: look at an overview of the data first, then zoom and filter it, then, on demand, consider the details.
