Drawing Algorithms for Linear Diagrams
semanticscholar(2021)
摘要
It is known that drawing linear diagrams with few line segments produces cognitively effective diagrams. However, methods to minimise the number of line segments in a diagram have not been investigated. In this Abstract, we report on four different approaches to drawing linear diagrams: creating a drawing order based on sets; creating a drawing order based on set-intersections; simulated annealing; and a transformation to another problem, in this case the Travelling Salesman Problem (TSP). We tested each of these approaches on a corpus of 440 linear diagrams with a range of characteristics. The algorithm which produced the lowest number of line segments in a diagram was based on the Lin-Kernighan algorithm for solving instances of TSP. The second contribution of the work is the corpus of 440 linear diagrams, which can be used as a benchmark set of problems for others who seek other solutions to the problem of drawing linear diagrams.
