Synonyms – Is ‘Joint’ a Synonym for Place?

People sometimes call cartilage "soft bone". This is used in the context of eating, as in, "Johny, you can eat the soft bone on that chicken drumstick, you know!". "Soft bone? That's silly, mommy!"

The Wikipedia page "http://en.wikipedia.org/wiki/Soft_bone" redirects to Cartilage.

People are justified in using "soft bone" because cartilage is related to bone. Some cartilage projects from bone, and continues the same shape or profile. Some cartilage turns into bone via ossification.

This is not a synonym per se, in my opinion, but if I understand your intended meaning correctly, you could use this word:

optimal (or optimum)
^adjective
best or most suitable within a range of possibilities

Other possible words came to mind are ideal, suitable, favorable, or simply best.

Another note: I think your sentence would sound better without the word location, and I would use user interface rather than visible interface, and maybe users instead of consumers. Thus,

The monitoring component is the user interface which the users interact with to visualize the optimal routes.
