d3-vector

A module for forceSimulations to define connections between nodes as directional vectors, consisting of angles within a cone of dispersion, and magnitudes defined either by a constant or by a function of the individual vectors. Reverse-engineered from the Link force by Mike Bostock.

Usage

Public methods on vector are all defined on the force object at the bottom of vector.js.

• force.initialize: begins running the simulation
• force.nodes: the data used for each node
• force.vectors: the connections between nodes, defined as an array of source and target objects
• force.id: a function to allow the simulation to internally identify each node for updates
• force.iterations: (ADVANCED) I'm not really sure... it's just kind of a thing that Mike made work and it affects how strongly your force is applied during the simulation
• force.orientation: the basis degree for orienting the angles of force.cone
• force.direction: 'reverse' will invert the cone of dispersion
• force.strength: a relative multiplier that affects the potency of each vector while the simulation is running
• force.magnitude: either a constant number indicating the length in pixels of each vector, or a function applied to each vector to determine its relative length
• force.cone: an interpolative scale that is applied to a raw degree value to coerce the vector to go in a specific angle relative to its source
