OpenOffice.org's tools for creating diagrams are easy to ignore. For one thing, their controls are extremely small. For another, they are pitifully under-documented in the online help, which plods through the options without explaining what they are or why you want to use them. Then, just to really confuse you, the full set of tools is available only in Draw and Impress, although Write and Calc users might also want them. Yet despite these handicaps, OpenOffice.org's diagram tools work well enough that many users should find no need for more sophisticated tools such as Dia.
