You dig through a lot of your perks and character sheet in Fallout games. Bethesda upped the visuals for this in Fallout 4.
Where in Fallout 3 the list of perks were in shown in an unorganized manner, the new system puts the perks into categories based on their S.P.E.C.I.A.L. requirement making it easy to know which you can choose. Perks are accessible based on both your character level and S.P.E.C.I.A.L. level and perks have levels of their own.
The perk chart is now animated and looks really, really cool. The pip boy also has animations as well and both provide a very nice eye candy to look at when going through your stats.
