Chartjunk

Chartjunk refers to unnecessary or distracting design elements in a chart or graph that do not improve understanding and can even obscure the data’s message. These include excessive colors, 3D effects, heavy backgrounds, or decorative images that clutter the visualization. The goal of a good chart is clarity and accurate communication of information. Removing chartjunk helps viewers focus on the data’s story without distractions, making the chart more effective and trustworthy. In essence, chartjunk is any visual embellishment that hampers the viewer’s ability to interpret the data clearly.
