generator(options, formatter)

valid options:

  • mode can be tiles, batch, latlon, place, jsonp, or replay
  • minzoom
  • maxzoom
  • bbox (for batch and polyline)
  • maxBatch (for bench and polyline) - max number of points to generate
  • z (for polyline) - used to estimate tile size, which is used to generate point density

Mode Options:

  • tiles gives a z, x, y
  • latlon does width, height, lat, lon, zoom
  • jsonp generates numbers
  • place generates place names
  • batch generates a given number of random points within a bounding box
  • polyline generated a random encoded polyline within a bounding box

formatter takes a function that takes the data, like xyz coordinates or placenames, and turns them into output
