+# file-size-tree [![unstable](https://rawgithub.com/hughsk/stability-badges/master/dist/unstable.svg)](http://github.com/hughsk/stability-badges) #
+
+Take a list of file paths in Node, and get back an object matching d3's
+[hierarchy layout](https://github.com/mbostock/d3/wiki/Hierarchy-Layout)
+format. Great for making easy
+[treemaps](http://bl.ocks.org/mbostock/4063582) and the like.
+
+## Installation ##
+
+``` bash
+npm install file-size-tree
+```
+
+## Usage ##
+
+### `require('file-size-tree')(files)` ###
+
+Takes an array of filenames and returns an object in d3's hierarchy layout
+format. For example, this:
+
+``` javascript
+var fileTree = require('file-size-tree')
+
+fileTree([
+    __dirname + '/project/src/index.js'
+  , __dirname + '/project/src/README.md'
+  , __dirname + '/project/src/package.json'
+  , __dirname + '/LICENSE'
+])
+```
+
+Should result in this:
+
+``` json
+[{
+ "name": "project",
+ "children": [
+  {
+   "name": "src",
+   "children": [
+    {"name": "index.js", "size": 3938},
+    {"name": "README.md", "size": 3812},
+    {"name": "package.json", "size": 743}
+   ]
+  }
+ ]
+}, {
+ "name": "LICENSE",
+ "size": 526
+}]
+```
