The purpose of this research is to identify an additional method that may represent massive data efficiently, in addition to fundamental visuals widely present. The latter include but, are not limited to bars and charts. In short, the author shall address the issue via data visualization – a technique known to convey information and or share ideas. A user may opt for relevant hardware in accordance with his or her requirements, such as computing speed or graphical performance. For instance, a typical user would require the stipulated program on a web browser or machine (computer) with minimal setup. As such, the author had created a system well-suited in either case. For the reader’s interest, the topic encompasses several methodologies, all of which are not feasible nor may be implemented in the author’s context. To name a few, they are network, stream graphs and tree maps. The use of a hierarchical edge bundling diagram in a radial layout however, would be appropriate. Simply, this is attributed by a large number of samples to be computed. The mentioned structure consists of parent and child relations between data items which in turn, models a hierarchy or tree. For example, the technique may be applied to a corporate company where appointments are further sub-divided into others (Section 1.1). In relation to the previous paragraph, the author had modelled and custom-built a database of records to facilitate the involved. This was due to an absence in complete or appropriate datasets made available online. Also, external plug-in(s) and software(s) were necessary and included. All end-users shall derive at relationships between data items and associated concepts, on top of interactions with the designated program. The author had taken into consideration clarity and aesthetics as well, where clutter had been removed. With respect to Section 6 of this report, further enhancements to the system may be carried out in future.
