D3 treemaps with images

Can someone show me how to place images into a d3 tree map.
Eventually I’d like to nest 3 hierarchies, but for now I just need simple ‘flat’ tree map with about 20 images

          • Thank you , but the code you sent was way too difficult for me. I am just beginning at this and was hoping for something MUCH simpler- Just maybe 16-20 images- with only a single hierarchy (for now). Ideally to been, I want to just build a treetop with 20 images and be able to click on any of them and zoom that image to the root size. I want to use the treetop layout here because I eventually plan to have at least another level of nested levels and also be about to alter the data on the fly with cool transitions

          • Thank you , but the code you sent was way too difficult for me. I am just beginning at this and was hoping for something MUCH simpler- Just maybe 16-20 images- with only a single hierarchy (for now). Ideally to been, I want to just build a treetop with 20 images and be able to click on any of them and zoom that image to the root size. I want to use the treetop layout here because I eventually plan to have at least another level of nested levels and also be about to alter the data on the fly with cool transitions

          • Thank you , but the code you sent was way too difficult for me. I am just beginning at this and was hoping for something MUCH simpler- Just maybe 16-20 images- with only a single hierarchy (for now). Ideally to been, I want to just build a treetop with 20 images and be able to click on any of them and zoom that image to the root size. I want to use the treetop layout here because I eventually plan to have at least another level of nested levels and also be about to alter the data on the fly with cool transitions
