# EllipseGraphics

#### new Cesium.EllipseGraphics(options)
DataSources/EllipseGraphics.js 49

  Describes an ellipse defined by a center point and semi-major and semi-minor axes. The ellipse conforms to the curvature of the globe and can be placed on the surface or at altitude and can optionally be extruded into a volume. The center point is determined by the containing `Entity`.
