In the reading today the authors discussed many rhetorical devices used to help a reader understand an example of visual rhetoric better. In the first reading, the author discusses the use of dashed lines in visual rhetoric. Dashed lines are less strong and are usually used to show future things or to de-emphasize the importance of the outlined object. They also wrote that dashed lines are easiest to understand when the dashes are close to each other and of similar spacing. In another reading, the author attempts to explain why it is important to not distract the audience with more than one set of information at a time. The author gives an example of a diagram for oil pollution where the detailed information needs to be read separate from the picture in order to understand the point of the the diagram. In the third reading, the author tries to tell the reader that the use of animations should only be used when it is helpful in guiding the reader and that the animation should not become unbearable or annoying. An example is given where a website would play an animation when using the menu that took a long time to finish and easily annoyed the reader.
One example of visual rhetoric that is famous and relates to the readings for today is the Indian Jones series. In the movies when Indiana is traveling across the world his movements are depicted as a dashed line on a map staring from where he begins and where he ends. This visual is very effective because it shows the progression in an easy to understand fashion and with the use of dashed lines it shows that the route he travels is not permanent but a temporary one that doesn’t always follow the roads and designated paths.
Here is a clip from the comic Family Circus. The use of dashed lines here shows the path that the child followed on his way to the bus. How does the use of dashed lines give a more clear understanding than if the author used a solid line? Where would it be appropriate in motion to use a solid line instead of a dashed line?
