The Dolphin in the Rose
A classic optical illusion used to explain elements of human memory and perception is a picture of a rose with a dolphin hidden in the rose’s petals. Take a look at the original image.
Use data graphics that clearly and obviously show a trend, relationship that maps to the chart that is design to show the particular insight. Your audience is looking for common or familiar patterns. For example, a picture of a dolphin in a rose is not what we expect to see.
Make the insight easy to spot. Reduce data density. Select a chart type that shows the findings without extraneous explanations.
Make sure your insight isn’t the dolphin hidden in the rose.
