check this out! type in a disease in the search box and hit ‘enter’ on your keyboard. select the disease by clicking on it. in the middle frame you’ll get a hierarchical view of your search term in tree form, and in the right frame you’ll get the term at the center of an information explosion. click on the exploded terms to see how they relate to your search term.
