Draw Venn diagram using Java

Question

I'm trying to draw a Venn diagram from a given boolean equation e.g (a AND b) AND c I want to do this on an android phone so I need to find a way to do it using Java.

I found a perfect widget that does everything I am looking for in this Boolean Algebra Calculator

They create perfect diagrams, I am sure it's not using Java and neither could I see their logic.

I would appreciate any API, algorithm or guidance.

I am reminded of this [Q&A](http://stackoverflow.com/q/11337679/230513). — trashgod, Jul 28 '12 at 00:34

It uses a WolframAlpha widget to generate the Venn diagram. Luckily for you, WolframAlpha offers an API for this kinda stuff.

Though I'll admit, it's a bit overkill. And you have to be connected to the internet to use it.

There are Venn diagram drawing solutions for Java such as charts4j. But if you use those, you'll have to manually compute which regions are highlighted.

Yeah saw that widget, but I'm trying to find away to do it offline on an android phone. Is there away around that or an alternative ? – Achilles Jul 28 '12 at 00:35
I doubt that there is a library that does exactly what you say given a boolean expression. You'll likely have to do the computation yourself and use a library to do the rendering. – tskuzzy Jul 28 '12 at 00:36
I mentioned one in my answer. – tskuzzy Jul 28 '12 at 00:41
Cheers mate, I guess its computation will not be an easy job. – Achilles Jul 28 '12 at 00:45
