Charts and graphs and diagrams are not just for boring old worklife. Check out this series of valentines day inspired charts: Why you should continue to date me; a series of charts and graphs. by Joel A. Friesen.
I personally think that if that doesn't convince you of the power of love and the power of the clear presentation of information, nothing will. However if you're still not in a valentines day mood, see how love conquers hate at google trends.

Thanks to information aesthetics for those links.

What did I do for valentines day? I wish I'd thought of charts and diagrams! Instead I went for a mosaic. Happy valentines day!
