        strength: Set the force of attraction for the edges. A high value results in having nodes together.
                The default value is 1.0
        charge: Typically a negative value. E.g., -300.
                This is a repulsive force between nodes (like electric charge).
        length: the natural (desired) distance between connected nodes, eg. 50
        gravity: it is the force from nodes to move toward center.
                Higher value results in nodes clustered more tightly toward the center.
        friction: Simulates resistance or damping in motion — it slows down node movement over time.
                Usualy a value between 0 and 1. Higher value makes nodes slow down quickly and the layout stabilizes faster.
        theta: Theta coefficient from Barnes-Hut simulation. Value ranges on [0, 1].
                Performance is better with smaller values. 
                Very small values may not create enough force to give a good result"
