The visualisation is based on findings of an data analysis. It showed that the relations of each entry are defined through different relation levels. An entries position and area is described through its direct related entries, and their related entries are describing the main entries position in more detail.

An entry has several relation levels, the first level are close connections of the entry, the second level is the close connection of the first level entries and so on. The entries of the first level describing the main entry and their related entries (the second level entries) are specifying the main entries position and interest area with more detail. This is because they are showing the first level entries interests and positions.
By looking at these two levels, the position and interest areas of the main level can be described.

After exploring different ways of defining a good dataset representation (which can be found here) the development focuses on typical data diagram visualisation. The reason for this decision is that many people know this kind of visualization and it is easy to understand.

The data representation is developed through transforming the segments belonging to the entries usage value (usage value - describes how often an entries is related to the main entry, for example: how often the keyword - blog - is used in relation - web -) and content value (content value - number of all related entries, it describes an entries size ). The usage value is used to calculate the angle of a segment and the content value defines the size of the segment, which shows the related entries in relation to the whole system. Each segment can be easily understood through its size and shape, and it describes a segment in more detail. (see documetation)

Five circles are added to the different sized segments. Theses circles represent the segments (related entry) top five related entries. Through this the visualisation shows the related entries of the main entry (first relation level) and their related entries (second relation level), which gives the user/viewer the possibilty to see and access the second relation level.
