When creating your visual in your graphing application (for example, Excel) and refining to get from good to great, you can leverage what I call the “optometrist approach.” Create a version of the graph (let’s call it A), then make a copy of it (B) and make a single change. Then determine which looks better—A or B. Often, the practice of seeing slight variations next to each other makes it quickly clear which view is superior.
A-B testing is "the optometrist approach"
