<P> Tufte encourages the use of data - rich illustrations that present all available data . When such illustrations are examined closely, every data point has a value, but when they are looked at more generally, only trends and patterns can be observed . Tufte suggests these macro / micro readings be presented in the space of an eye - span, in the high resolution format of the printed page, and at the unhurried pace of the viewer's leisure . </P> <P> He uses several historical examples to make his case . These include John Snow's cholera outbreak map, Charles Joseph Minard's Carte Figurative, early space debris plots, Galileo Galilei's Sidereus Nuncius, and Maya Lin's Vietnam Veterans Memorial . For instance, the listing of the names of deceased soldiers on the black granite of Lin's sculptural memorial is shown to be more powerful as a chronological list rather than as an alphabetical one . The sacrifice each fallen individual has made is thus highlighted within the overall time scope of the war . In Sidereus Nuncius Galilei presents the nightly observations of the moons of Jupiter in relation to the body itself, interwoven with the two - month narrative record . </P> <P> Tufte has criticized the way Microsoft PowerPoint is typically used . In his essay "The Cognitive Style of PowerPoint", Tufte criticizes many aspects of the software: </P> <Ul> <Li> Its use to guide and reassure a presenter, rather than to enlighten the audience; </Li> <Li> Its unhelpfully simplistic tables and charts, resulting from the low resolution of early computer displays; </Li> <Li> The outliner's causing ideas to be arranged in an unnecessarily deep hierarchy, itself subverted by the need to restate the hierarchy on each slide; </Li> <Li> Enforcement of the audience's lockstep linear progression through that hierarchy (whereas with handouts, readers could browse and relate items at their leisure); </Li> <Li> Poor typography and chart layout, from presenters who are poor designers or who use poorly designed templates and default settings (in particular, difficulty in using scientific notation); </Li> <Li> Simplistic thinking--from ideas being squashed into bulleted lists; and stories with beginning, middle, and end being turned into a collection of disparate, loosely disguised points--presenting a misleading facade of the objectivity and neutrality that people associate with science, technology, and "bullet points". </Li> </Ul>

According to tufte 2001 what is the main use of bullet points
