Followers of this blog would have seen me using a few websites to produce mind maps for various purposes. For a list of free mind mappers I've used, see the useful resources page.
To see examples of the mind maps in action, see Cokey Monkey, Ideas on a silver platter, and How to create an interactive mind map.
Lately, my favourite has been Spiderscribe in spite its having certain weaknesses; however, I'm pleased to announce that they have now allowed embedding, and exporting to either jpg or png format.
Below are examples of a png image, and an embedded map. These maps were used to demonstrate collocations of the word 'holiday', first seen on The Dogme Diaries, my reflective blog.
