When designing effective demonstrative evidence, you want to educate your jury,
not overwhelm them.

First, decide exactly what message you want the graphic to convey.

Second, gather the necessary information to support the chart.

Third, the key to creating a successful graphic is to keep it simple.

Don’t try to make too many points on a single chart. If additional points are necessary to tell the story, be sure to introduce the individual parts, one at a time, using a computer presentation, or a magnetic trial board.

Magnetic boards allow total flexibility in the courtroom. A magnetic timeline, for example, allows entries to be revealed as the testimony unfolds. The order in which the entries are uncovered, can change on the spot, at any time.

Magnetic Timeline 

 

* Remember, unlike a computer image that goes away when the next image is projected, a trial board can stay up in the courtroom.

Computer presentations allow you to present one point at a time with the click of a mouse. Your points will appear seamlessly as they are presented in the courtroom.

* Computer presentations are the way to go when there are numerous charts being presented.

Keep in mind, this is your case, so your graphics and delivery method should complement your presentation style.
