A picture is worth a thousand words


This
 
article presents an infographic that will help you pick a wine, based on various characteristics.

What I like about this graphic:
  • Illustrates the big picture: Users are provided with clear and consistent information and elements have been grouped in a logical manner. The infographic shows that there are 5 main varieties of white wines, that differ on several characteristics.
  • Depicts relationships: The infographic helps to easily associate related items and disassociate unrelated items.  For example, let us look at Chenin Blanc and Gew├╝rztraminer, both of which share the common theme of being a “semi-sweet” wine. Though both the wines are classified as semi-sweet wines, both appear to be very different from each other. While Chenin Blanc scores high on pear, almond, stonefruit, and fig flavors, honey and floral are the characteristic traits that represent Gew├╝rztraminer.
  • Is Aesthetic: The depiction inspires me to examine and understand the information that is presented. This is in striking contrast to textual or tabular information that do not provide an obvious affordance.
  • Creates visual interest: Shapes have been used very effectively to create contrast between the different wines, even within the same category.
