I am looking for some Mac software that will help me visually organize data into a tree-like visual. For a use case example, imagine an e-commerce site where you have to come up with categories, details, etc. So jeans then have options of fit/style, brand, color, etc, with everything rolling back up into jeans. And then the same for another category like jackets. Since this is tree logic, I would imagine there is some pretty standard software out there that someone might be so kind as to recommend?
