  // OPTIONAL
  minVelocity: 0, // used to align color scale
  maxVelocity: 10, // used to align color scale
  velocityScale: 0.005, // modifier for particle animations, arbitrarily defaults to 0.005
  colorScale: [], // define your own array of hex/rgb colors
  onAdd: null, // callback function
  onRemove: null, // callback function
  opacity: 0.97, // layer opacity, default 0.97

  // optional pane to add the layer, will be created if doesn't exist
  // leaflet v1+ only (falls back to overlayPane for < v1)
