I would like to wish all readers happy holidays and a healthy and prosperous 2010. From a presentation perspective, try to make a difference in 2010, for example:
Since Tel Aviv is bright, warm, and sunny today, and probably the only Xmas tree in the city is put up in my apartment, I actually enjoy watching some of these old masters that have been put too many times on post cards:
Pieter Breugel the Elder, 1565, Hunters in the snow, Oil on wood, 117x162cm, Kunsthistorisches Museum, Vienna
The colour is named after the orange fruit, introduced to Europe via the Sanskrit word nāranja. Before this was introduced to the English-speaking world, the colour was referred to (in Old English) as geoluhread, which translates into Modern English as yellow-red. The first recorded use of orange as a colour name in English was in 1512, in the court of King Henry VIII.
are great to show overlapping features. In practice however, it can be hard to position text in the circular shapes. I often use an adjusted version of the Venn diagram, one based on boxes. Boxes are easier to draw, and especially, you can make the center box (the most important one) really large.
As you can see below, I did not rely on semi-transparent colors to create the overlap effect. Rather, I just drew the third box in, giving me complete flexibility to decide on colors. Again something that would be hard to do in a circle Venn diagram.
UPDATE February 2018: I have now added a number of Venn diagrams in PowerPoint to the SlideMagic store, including the rectangular ones that are described above.
