线图是指用环状绳索在双手之间拉开，并通过各种方式在手指和手腕上扭曲和编织而产生的任何图案。可以使用纽结理论研究以这种方式实现的交叉组合。
上述线图被称为阿帕奇门 (Apache door) (Jayne 1975, pp. 12-15, Fig. 21) 或帐篷 flap (tent flap) (Ball 1971, p. 5, Fig. 2)。
上述图示的线图被称为“雅各的天梯 (Jacob's ladder)”，奥塞奇钻石 (Osage diamonds) (Jayne 1975, pp. 24-27, Fig. 50)，渔网或四重钻石 (quadruple diamonds) (Ball 1971, p. 19, Fig. 7)。
线图属于世界各地许多民族的古老传统，甚至在原始文化中也存在，如今被认为是数学教育中的一种娱乐活动。在英语国家，它们也被称为儿童游戏“猫的摇篮 (cat's cradle)”。
