How to read it

Prograde burns raise the other side of the orbit. Fire at periapsis to lift apoapsis; circle by firing prograde at apoapsis. Retrograde lowers the far side (deorbit from periapsis).

Try: launch LEO, fire prograde to raise apoapsis toward GEO, coast to apo, fire prograde again to circularize. Classic Hohmann transfer, minimum Δv to reach GEO ≈ 3.9 km/s.
