Fixed DBpedia Ontology Tree (Colored) II

README.md

This visualisation is an extension of the Fixed DBpedia Ontology Tree (Colored). It includes the class size that is the amount of entities of a certain class.

For instance, considering the RouteOfTransportation node on the top of the tree, its value (27,027) represents the number of entities labeled with a subclass of RouteOfTransportation or RouteOfTransportation itself. Hence, this value does not represent the number of entities labeled only with RouteOfTransportation. It is the number of entities labeled with RouteOfTransportation and all the subclasses belonging to the RouteOfTransportation subtree.

These values are considered in the circle radius of the nodes of the tree. This allows to compare two classes using their node size.

As in the previous visualisation the most important and significative classes, Person, Organisation, Work, Place, Species and Event has been colored respectevely with red, orange, purple, green, teal and blue.
