No matter what design tool you use (PowerPoint, Adobe, Tableau, etc.), there are seven deadly mistakes made consistently by both expert and novice data designers. When your visualization is False, Haphazard, Textual, Questionable, Confusing, Repetitive, or Verbose it's highly likely that the audience will be confused, may ignore your design, and you can severely hurt your credibility. 

A well-designed data visualization is easy to understand and much more likely to be remembered by the audience. This talk will explore examples of these top seven mistakes designers often make, and more importantly, offers design tips to overcome these common blunders when your design is:

  • False - Accuracy is the most important aspect of a visualization
  • Haphazard - Data should be well thought out with key messaging and a clear purpose
  • Textual - Using text-only data provides no context for readers, and is viewed as less important
  • Questionable - Give your audience a reason to trust you with data transparency
  • Confusing - Learn the difference between bad complexity that confuses readers and good complexity that invites engagement
  • Repetitive - Don't use the same chart style over and over again - break out of the Big Three charts: Bar, Line and Pie
  • Verbose - The first impression is everything, and too much information at first glance will turn your audience away


Following the educational session (10-11), the presenter will remain online for a 30-minute informal discussion with those interested. Note - depending on the audience size, we may "open the microphones" for this part, so you may wish to have a headset with microphone or call in. (Typed questions will still be accepted also.)


This free webinar is open to any public sector employee interested in the topic.
