title: Can I use images as the background rectangles for d3 treemaps?
body: <p>Is it possible to make a treemap in d3 with the background of each rectangle be an image? I am looking for something similar to what was done in Silverlight <a href="https://stackoverflow.com/questions/17618733/using-a-treemap-with-images">here</a>, but for d3. If it is possible, are there any recommended tutorials that walk through the process of connecting the background to an image?</p>
