地图显示与图标技术的结合非常适合于可视化地理空间相关的多变量数据。在地图上放置图标的要求，虽然不是微不足道的，没有适当地参加了大多数交互式可视化系统。在制图学中，已经开发了许多用于自动文本标注放置和地图综合的方法。这些都集中在高质量的结果，导致响应时间长，不适合交互式环境。本文提出了一种借鉴制图方法的交互式、可扩展的方法，该方法基于图标的迭代位移并结合焦点和上下文技术。
The combination of map displays with icon techniques is well-suited for visualizing geospatial dependent multivariate data. The requirements for icon placement on the map, although not trivial, are not properly attended by most interactive visualization systems. In cartography, a number of methods for automatic text label placement and map generalization has been developed. These are focused on high-quality results, leading to long response times not suited for interactive environments. In this paper an interactive, scalable approach borrowing from cartographic methods is presented which is based on an iterative displacement of icons combined with a focus & context technique.
