Brooklyn says hi. :) Let me say that even this simple demonstration of charts looks amazing - this really brings up a lot of possibilities. However, I think it's a bad idea to include this code directly in SMW. The Google Charts service is free, but it's not open source, which means that (a) they could start charging for it at any time, and (b) the whole project now becomes reliant on this URL staying up. Even if neither of those ever become a real issue, there may be companies and organizations that have a strict open-source policy for the applications they use, and SMW would now violate those. I think this code is much better off getting packaged as a "Semantic Google Charts" extension, using the same hooking-into-the-ask-query approach that Semantic Google Maps now takes. I don't know if I should be the one to do that (I guess we can talk about that). But if that happens, it still would be nice to have an open-source graphing library directly within SMW - that JpGraph library looks like a good one, although the graphs it creates look ugly as sin compared to Google's - maybe that can be changed.

wow! I'm impressed! I will definitely give it a try.

The problem is that I'm no PHP developer. So I can add something here or
there and provide translations, but I have not the skills to take over a

But I know someone who is doing a great job in taking over other's somewhat
abandoned projects ;-)

[hint] greetings to brooklyn [/hint]

Regarding library, maybe is worth considering?
