 * Position nodes using the ForceAtlas2 force-directed algorithm.
 * @param G - Graph
 * @param pos - Initial positions for nodes
 * @param maxIter - Maximum number of iterations
 * @param jitterTolerance - Controls tolerance for node speed adjustments
 * @param scalingRatio - Scaling of attraction and repulsion forces
 * @param gravity - Attraction to center to prevent disconnected components from drifting
 * @param distributedAction - Distributes attraction force among nodes
 * @param strongGravity - Uses a stronger gravity model
 * @param nodeMass - Dictionary mapping nodes to their masses
 * @param nodeSize - Dictionary mapping nodes to their sizes
 * @param weight - Edge attribute for weight
 * @param _dissuadeHubs - Whether to prevent hub nodes from clustering (unused)
 * @param linlog - Whether to use logarithmic attraction
 * @param seed - Random seed for initial positions
 * @param dim - Dimension of layout
 * @returns Positions dictionary keyed by node
