The class on October 14th, the sixth class of Systems Visualization, added a new term and concept to the class: ‘Ontologies’. By the end of the class, they learned that an ontology gives meaning at an underlying level to the content/data, from which the reality of the connections across the system nodes and links can be more easily represented.
Though taking the class by surprise, Dr. Shiva was able to explain the significnance of Ontology in Systems Visualization. He explained that the purpose in reviewing Ontologies is to demonstrate that they make visualizing complex systems far easier than without them. Complex systems are not just the data (as in other fields of data and information visualization) and not just a visual metaphor (as in advertising), but require the connective integration across the whole and the parts by emphasizing the connections.
In many ways, as you will begin to see Systems Visualizations are connections of “scenes” in a “story”. These connections are the key to Systems Visualization. And connections need a representation format or language. This format and language are ontologies. While Ontology may be less important to static or dynamic data visualization, the class learned that Ontologies are critical to Systems Visualization.
Class was given a reading assignment to understand how Ontologies are becoming critical in representing visual scenes.

Systems Visualization Class Of October 7, 2011
The fifth class held on October 7th, 2011 discussed Visual Metaphors and Representation Using Graphs and Trees. Based on the recognition that Visual Metaphors were critical as the “front end” for driving the messaging of Systems Visualization, the class reviewed some of the basics of Visual Design to provide principles in the design of the → Read More

Systems Visualization Class Of September 30, 2011
In the fourth class of Systems Visualization held on September 30, 2011, students recognized the importance of Visual Metaphors to quickly evoke an emotion beyond the “nodes” and “links”. The class began with a review of a digram presented by one of the students (See Figure 1 below.) The diagram caught everyone's → Read More

Systems Visualization Class Of September 23, 2011
On September 23rd, M.I.T. Department of Biological Engineering’s third Systems Visualization class was held. While the first classes discussed Systems, this class focused on Visualization. Dr. Shiva started the class with an explanation of what visualization is. He also gave a historical review of visualization. The class went through → Read More

Systems Visualization Class Of September 16, 2011
Friday 09/16/11 was the second class of Department of Biological Engineering’s Systems Visualization class. at M.I.T. The class was moved to a larger room to accommodate the large student turnout. Dr. Shiva started the class reviewing different types of systems. First, the class reviewed what is an ‘Open System‘. Open systems receive Input/s, perform → Read More

Systems Visualization Class Of September 9, 2011
The first class of Systems Visualization for the Fall 2011 semester at M.I.T's Department of Biological Engineering was held on 09/09/11. Dr. V. A. Shiva had reserved the classroom expecting to see fifteen students who had already registered for the class. However, within twenty minutes of starting the class, Dr. Shiva was scrambling to find more chairs → Read More
