我尝试使用NodeXL并导出文件并导入Gephi.但是,我无法找到一种方法,可以在节点属性的基础上在世界地图上显示它.
另外,我知道D3.js,但我找不到任何关于地图上网络的示例或教程.

我有两个div并排.它们都没有标准高度,但是第一个具有内容,而另一个在表单子项后填充内容.我想将第二个的高度设置为与第一个相同.
这是html:
<div id='left'>
...........
</div>
<div id='right'>
...........
</div>
<script type="text/javascript">
$(document).ready ( function(){
var divHeight = document.getElementById('left').style.height;
document.getElementById('right').style.height = divHeight+'px';
});?
