Drawing Network Visualizations on a Continuous, Spherical Surface

Dario Rodighiero

Despite the great literature regarding network visualizations, their graphic representation is hardly an object of investigation. Sometimes it is worth more attention, especially when individuals are represented. Visually translating communities in networks, for example, implies that some individuals are always situated at the borders of the representation. This assumption is clearly unfair, especially if each individual of the community is connected with everybody else. To solve this lack of design justice, the community is represented on a spherical network where the surface is continuous. In that space, individuals can be situated in a sparse area, but never on the edges. The spherical network is successively projected on the flat surface to improve the network readability making use of cartographic projections.
