Envisioning Information- Chapter One

By on

I think the most important principle mentioned in Chapter One is that of small multiple. This means that the same design structure is repeated for all of the images. Tufte says, "Once viewers decode and comprehend the design for one slice of data,they have familiar access to data in all the other slices" (29). He also notes that the consistency in the design allows the viewers to focus on changes in the information rather than the graphical changes. He uses an example of air pollution, but this also applys to the LSAT table. This graph is displaying a combination of information- the number of applicants and the number admitted by this particular law school. There is alot of information displayed here and the reader can get easily confused. It is crucial that the audience be able to understand this graph and not to make it look clustered. I think this is the most important principle because we have to be careful with this when we do our projects. Tufte also mentions, "Disrespect for the audience will leak through, damaging communication" (34). Visual displays can be perceived in many different ways by many different people, so this concept is extremely important to remember.
