Example service: Searching
Search diagrams for a specific name or text (this is googles search):
Example service: Visualization
Example service: Visualization (this is the Luchaire network read as JSON with a script using d3). The nodes are linked with Wikipedia.
Please notice that this is not about imitating the drawings. It is a visualization of the datastructure which is interactive: The nodes link to other information, that is the value added. In this case we use a very simple mechanism to hope for Wikipedia content for the nodes name. But this can be anything more advanced also. It could link to another diagram in which the person or institution also appears or to specifically curated information of very high class.
