  multiple font families, separated by commas, to indicate the
  preference in which to apply fonts if they aren't available on
  the system. The Chart Studio Cloud (at https://chart-

  where only a select number of fonts are installed and
  supported. These include "Arial", "Balto", "Courier New",
  "Droid Sans",, "Droid Serif", "Droid Sans Mono", "Gravitas
  One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans
  Narrow", "Raleway", "Times New Roman".
