How to add content to the layout

[Leo-lin214]

The justified layout is great, but I don't know how to add content to the layout and can you give an example?

The [demo page]() uses the returned geometry to render boxes.

Here's the crux of the code:

var geometry = justifiedLayout(input, config);
var boxes = geometry.boxes.map(function (box) {
   return  `<div class="box" style="width: ${box.width}px; height: ${box.height}px; top: ${box.top}px; left: ${box.left}px"></div>`;
}).join('\n');

@jimwhimpey Why not put that sample in README.md ?
