Here are the various geometric shapes you can draw using JavaFX

Line - A line is a geometric structure that connects two points. javafx.scene.shape. Line Class represents a line in the XY plane.
Rectangle - A rectangle is a four-sided polygon with two pairs of parallel and concurrent sides, and all interior angles are right angles. javafx.scene. Rectangle Class represents a rectangle in the XY plane.
Circle strong> - A circle is a line forming a closed loop, with each point on it being a fixed distance from the center point. javafx.scene. Circle Class represents a circle in the XY plane.
Ellipse strong> - An ellipse is defined by two points, each called a focus. If you take any point on the ellipse, the sum of the distances to the focus is constant. The class of javafx.scene.Ellipse represents an ellipse in the XY plane.
Polygon > - A closed shape formed by many coplanar line segments connected end to end is called a polygon. The javafx.scene.Polygon class represents polygons in the XY plane.
Polyline - A polyline is the same as a polygon, except that the polyline is not closed at the end. Or, a continuous line consisting of one or more line segments. The javafx.scene.Polyline class represents a polyline in the XY plane.
Cubic curve strong> - A cubic curve is a Bezier parametric curve in the XY plane and is a cubic curve. javafx.scene.CubicCurve Class represents a cubic curve in XY
QuadCurve - A quadratic curve is the XY plane The Bezier parameter curve in is a quadratic curve. The javafx.scene.QuadCurve class represents a quadrilateral curve in the XY plane.
Arc - An arc is a portion of a curve. The javafx.scene.Arc class represents an arc in the XY plane.

To create the desired shape you need to instantiate the appropriate class.

Set its properties.
Add the created object to the group.
