The philosophy behind the use of the charts at this site is based on the fact that there is a link between music theory, mathematics, and the physical positions of notes on a fretboard. When learning music theory and applying it to an instrument such as the guitar or bass, the application of that theory manifests itself in note positions on a fretboard. It is my belief that using visual representations of this theory can aid in learning and allow a musician to more thoroughly exploit scales, chords, and arpeggios that may be too complex to easily visualize in the mind.
