Octilinear Force-Directed Layout with Mental Map Preservation for Schematic Diagrams

Improving automated layout techniques for the production of schematic diagrams

This thesis explores techniques for the automated production of schematic diagrams, in particular those in the style of metro maps. Metro map style schematics are used across the world, typically to depict public transport networks, and therefore benefit from an innate level of user familiarity not found with most other data visualisation styles. Currently, this style of schematic is used infre...

Drawing Metro Maps Using Bézier Curves

The automatic layout of metro maps has been investigated quite intensely over the last few years. Previous work has focused on the octilinear drawing style where edges are drawn horizontally, vertically, or diagonally at 45◦. Inspired by manually created curvy metro maps, we advocate the use of the curvilinear drawing style; we draw edges as Bézier curves. Since we forbid metro lines to bend (e...

Force - Directed Layout for Euler Diagrams Luana

Euler diagrams are the only diagrams that intuitively represent containment, intersection and exclusion of data, but none of the current automatic diagram layout techniques produce good layouts in a reasonable time. We adopt a force-directed approach to automatically layout aesthetically pleasing Euler diagrams in a relatively fast time. A Java prototype demonstrates our novel force model.
