/**
 * Specify the data encoding to supply to the Google Chart API. The only
 * advantage to the simple encoding scheme is it will ultimately result in
 * shorter URLs, but at the cost of lower resolution. charts4j defaults to
 * extended encoding, but if you have lots of data and if you are willing to
 * sacrifice resolution, the simple encoding may be right for you. Text encoding
 * was included for the sake of completeness. Text encoding has limited
 * usefulness other than perhaps debugging. It should probably be avoided unless
 * you want to see the actual data in the URL at the cost of a much longer URL.
