The Six Degrees of Francis Bacon project is an open source, collaborative work designed to visualize connections between Francis Bacon and other early philosophers and scholars in their work based on data located in a database full of texts. The primary collaborators consist of members of the Carnegie Melon University Libraries, where the website is hosted, however, the project has received support from a variety of sources (more about history of project).
The nodes represent individual scholars, and the edges represent the relationships to other scholars in the network. The title of the project, Six Degrees of Francis Bacon, is indicative of the parameters of the network: nodes are made up of people as distant as 6 degrees away from Bacon (6 connections link Bacon and the most distant nodes).
Additional visual cues make the graph easier to interpret. For one, the size of nodes are greater the closer the individuals are in relation to Bacon. Also, individuals directly connected to Bacon (with a degree of 1) have a shaded node, whereas more distant nodes are empty.
Among the coolest features of the network is the informative pop-up for a node when clicked. By clicking on a node, all edges and nodes fade except for those immediately connected to the node and an informative pop-up appears in the top left corner detailing the name of the individual and their lifespan. It also has a Visualize button which triggers a modified network to be presented where the individual is the root node and all distant connections are included (just as the default network appears, but Francis Bacon is the root node).
