The basic design of a treemap is where a diagram utilizes rectangles to help format the information to help recognize patterns where data is abundant and hard to categorize. This tool is great for presenting the data and with the help of colors and other key symbols it can be used to find patterns and trends within experiments to highlight important outliers or commonalities. This tool is very easy to understand due to its simplistic design of organizing data into something that is easy to view. Now with this design many users can learn to appreciate this tool and use it more for analyzing data (Shneiderman, 1998).

As more data gets collected in health informatics, more tools need to be developed to help users make a more educated decision on what actions are considered beneficial or detrimental. In one scenario colors of green and red were used to help users see with a corresponding action what caused a patient to survive and others to die. As this tool grows I can see it providing users more information per rectangle in real time and can be used more on the fly to help give patient faster and more efficient health care (Hugine et al, 2014).
