As more and more research proves that visuals increase information clarity and retention, charts and diagrams continue to play a prominent role in presentations.  But, there is a right way – and a wrong way – to structure and use them.  Proper chart and diagram construction is critical to conveying your concepts in the best possible way.

Choose the right chart for the right data.

Here are five proven tips for designing effective charts and diagrams:

1. Choose the Right Chart for the Right Data

There are countless chart and diagram styles to choose from, each ideal for presenting specific types of information.  For example, pie charts work well when you are demonstrating parts of a whole (i.e. percentage of total revenues by product), while bar charts clearly convey data variances among different items or groups (i.e. student enrollment by course).  Changes in statistics or data points over time are best displayed using line charts (i.e. sales by month).  And, maps are great for presenting information in the context of a physical location (i.e. where customers live, or where branch offices are located).

Avoid tabular displays whenever possible.  Although they may seem like the best way to logically organize and lay out large data sets, audiences will find them dull and boring.  Look for more creative and visually appealing ways to share this type of information.

2.  Stick to One Message per Diagram

Charts or images that include too many data sets, ideas, or points will be sloppy, cramped, and hard to read.  Stick to one simple idea per diagram, to avoid confusing or distracting your audience.

3. Label Everything Clearly

Charts without correct labels, or labels that are difficult to read, are limited in their value.  Be sure everything is labeled accurately, and that you use font types and sizes that will be easy for participants to see, so they can refer to the image as you are explaining it.

4.  Incorporate Builds

Some diagrams – particularly those that are mechanical or technical in nature – can be quite complex.  The more components your diagram contains, the harder it will be for your audience to absorb it.  Try using builds to bring in the various elements, one at a time.  This will simplify the concept you are trying to present, providing attendees with a better understanding of the diagram’s individual components, and how they work together as a whole.

5. Use Color Wisely

Proper use of color will not only make your chart or diagram more stunning and attractive, it will make it more meaningful and understandable.  Strategic use of shades and hues can help instantly outline differences in data points, as well relationships and similarities among them. But too much can be a distraction, so try to use no more than four or five different colors per slide.
