Just wondering what's the wiring, kinda confused on how this actually looks on a schematic.
Does this look correct?

It's a (simulated) variable resistor between pins 5 and 6. From Wikipedia:
Of course there are some differences with real resistor, such as the requirement that both ends of the resistor must always remain within the power supply rails of the chip for proper operation. The "wiper resistance" is in series with the "element resistance" which means some nonlinearity that will vary with voltage of the simulated rheostat and the supply voltage.
Yes you are right.
you can find on page 2 of the datasheet this schema :
