Here is a site I came acrosss by change.  A periodic table of visualisation methods.

The periodic table of elements lists the elements in nature and they show elements properties are repetative.  I am not sure this table does exactly show that for visualisation methods, but if you need to make numbers or concepts understandable then these examples may help.
