| Abstract: | With terrorism aggravating,anti-terrorism has been a main task for national military security departments around the world.The current study utilized categorical data visualization,Parallel Sets,to analyze the relations among the multi-categories in Global Terrorism Database,aimed to uncover the implicit information within the data set.To alleviate the deficiency of excessive edge crossing brought by random layout of categorical values,the research proposed a heuristic layout algorithm based on average heur... |
