Computer scientist Keith V. Nesbitt’s hand-drawn map, which was inspired by the Sydney metro map, shows interconnecting ideas running through his Ph.D. thesis. Nesbitt’s thesis concerns the design of multisensory displays of abstract data with the motivation of mining this data. On the map, each separate “track of abstract thought” in the thesis is represented by a different color. Related ideas correspond to category stations along that track. Overlapping ideas are shown as connected stations. The familiarity of metro maps makes the diagram easy for readers to interpret. As the space in which the tracks are laid is invariant to rotation and mirroring, it is possible to read the map in any direction. However, there is a cultural bias for the tracks to be followed from left to right and top to bottom.
