The document discusses the importance of including a time component when presenting data in charts and graphs. It argues that without understanding the time period represented, it is difficult to properly interpret results and make informed decisions. The document provides examples showing how breaking down revenue data by month revealed different trends than when presented as aggregate six-month data. It promotes adding a "Time Value Bar" to charts to explicitly indicate the time period of the data to help audiences understand time as a critical aspect of analysis and decision making.
