仅显示单个州的完整美国县地图中的县 [英] Display only a single state with counties from a full US counties map

问题描述

是否可以在完整的美国县地图上显示一个州?

Is it possible to display a single state from a full US counties map?

我知道我可以获取每个州的形状文件和县，并创建topojson，但是如果可能的话，我宁愿使用一个文件.

I know I can get each states shape file and counties and create the topojson, but I'd rather work with one file if thats possible.

例如，以迈克·波斯托克(Mike Bostock)的美国全县地图为例.美国县地图这样可以只显示纽约吗?

For example take Mike Bostock's full US county map. US Counties Map Would it be possible to show just NY from this?

我还没有看到任何显示这种功能的示例.

I haven't seen any examples showing that type of functionality.

推荐答案

我最终完成了边界框，并在要显示的状态周围创建了剪切路径.

I ended up working off of project to bounding box and created a clipping path around the state I wanted to display.
