通过想像正方形网格或六边形单元，可以方便地可视化数据结构(实践中，应用程序在多数情况下采用正方形网格)。
You can easily visualize the data structure by imagining a grid of square or hexagonal cells. (in practice, applications use square cells most of the time.)
您可以通过从一个模式或 XML 文档的树型表示中选择示例结果节点，并将这些节点拖放到一个返回网格中，从而可视化地构造一个 XML 查询。
You can build an XML query visually by selecting sample resultant nodes from a tree representation of a schema or XML document and dragging the nodes onto a return grid.
此外，在此简化算法的基础上，还提出一个递进网格传输的框架，并实现了一个基于浏览器的可视化原型系统。
In addition, based on this simplification algorithm, a framework of progressive mesh transmission is also implemented as a browser-based visualized prototyping system.
