Here are 6 simple design tips to keep in mind :
Use no more than five colors in a single layout. Color should be used sparingly to highlight important information.
Present content in a way that guides readers through in a logical hierarchy. Aligning the elements in a layout with each other will help maintain consistency.
Keep significant negative space. When too much information is in a layout, messaging becomes cluttered and incoherent.
Icons should be simple, easy to understand and universal. Remember that they’re meant to enhance comprehension, never distract.
The eye can be deceiving; make sure items are appropriately sized in data visualizations so as not to skew data.
Avoid unnecessary design, including 3D charts, ornamental illustration, or extraneous elements. Remember, too, that minimal design can also be effective—so long as you have a strong story.
