What term refers to superfluous material that distracts from the data being displayed on a graph?

• A. Axis
• B. Chartjunk
• C. Gridlines
• D. Legend

Answer: (B)

In data visualization, the term for superfluous material that distracts from the data being displayed on a graph is chartjunk. This concept, popularized by Edward Tufte, covers any decorative or irrelevant elements—such as excessive colors, 3D effects, background patterns, or other ornamentation—that do not convey data and can mislead or overwhelm the viewer. The axis and gridlines, by contrast, are essential for interpreting values: the axis provides the scale, and gridlines help readers compare data points accurately. A legend is also a legitimate part of a graph when it explains what the symbols or colors represent. Those components aid understanding rather than distract, which is why chartjunk is the best description for extraneous features.
