抽象的。流动地图一直服务于人们探索运动表示的起点-目的地数据（OD数据）。由于数据收集技术的最新发展，运动数据量急剧增加。有了如此大量的数据，流图中的视觉混乱正在成为一个挑战。本文回顾了流量图，概述了OD数据的特点，并提出了一个分类系统的流量图。为了处理视觉混乱的问题，3D流图被提出作为2D流图的潜在替代方案。
Abstract. Flow maps have long been servicing people in exploring movement by representing origin-destination data (OD data). Due to recent developments in data collecting techniques the amount of movement data is increasing dramatically. With such huge amounts of data, visual clutter in flow maps is becoming a challenge. This paper revisits flow maps, provides an overview of the characteristics of OD data and proposes a classification system for flow maps. For dealing with problems of visual clutter, 3D flow maps are proposed as potential alternative to 2D flow maps.
