// This file holds definitions of all standard shape figures -- string values for Shape.figure.
// You do not need to load this file in order to use named Shape figure.

// The following figures are built-in to the go.js library and thus do not need to be redefined:
//   Rectangle, Square, RoundedRectangle, Border, Ellipse, Circle,
//   TriangleRight, TriangleDown, TriangleLeft, TriangleUp, Triangle,
//   LineH, LineV, None, BarH, BarV, MinusLine, PlusLine, XLine
// If you need any of the other figures that are defined in this file, we suggest that you copy
// just those definitions into your own code.  Do not load this file unless you really want to
// define a lot of code that your app does not use and will not get garbage-collected.

// See also the figures defined in the RoundedRectangles.js file.
