According to David McCandless, the Ted speaker of “The Beauty of Data Visualization”, presentation aids can be invaluable if presented as just a bunch of numbers. Presentation aids are useful is expressing data to the audience. The audience will not grasp the numbers presented unless it is appealing to them. McCandless mentions that a presenter should always dress up the numbers, to make it more interesting. He also told to keep minimum numbers to get the point across. It is important that the audience does not get overwhelmed by numerous numbers. If the visual aid is confusing for the audience, it will easily be overlooked.
