College students and even graduate students are the ones who often use diagrams, formulas and graphical representations. And yes, even corporate people who are in operations or planning departments make use of various graphical representations. And this reminds me of a compilation/table of the most frequently used diagrams or graphical tools that is called Periodic Table of Visualization Methods.
I find this tool handy because though there may be few other graphical representations that are not here, I can say that this is very useful link that deserves to be bookmarked as it have the most commonly used diagram that you can utilize on your decision makings, reports or presentations. It is modeled after the periodic table of elements but each element or square here represent various visualization method like Ishikawa’s diagram, parameter ruler, life/product cycle diagram to semantic network.
