Question

I want to make a website like http://newsmap.jp, Is there is any plugin that can help in the UI of the map?

Notice that there is no empty spaces in it.

Answer 1

Check out the jQuery Masonry plugin. Just call it directly on your container:

$('#container').masonry({
    itemSelector : '.itemsClassName',
    columnWidth : 240 // or whatever
});

There many more options, as outlined in the documentation.
