```
public CircleLayout(edu.uci.ics.jung.graph.Graph<V,E> g)
```
    Creates an instance for the specified graph.
- Method Detail
  - getRadius
```
public double getRadius()
```
    Returns the radius of the circle.
  - setRadius
```
public void setRadius(double radius)
```
    Sets the radius of the circle. Must be called before initialize() is called.
  - setVertexOrder
```
public void setVertexOrder(java.util.Comparator<V> comparator)
```
    Sets the order of the vertices in the layout according to the ordering specified by comparator.
  - setVertexOrder
```
public void setVertexOrder(java.util.List<V> vertex_list)
```
    Sets the order of the vertices in the layout according to the ordering of vertex_list.
  - reset
```
public void reset()
```
  - initialize
```
public void initialize()
```
    Description copied from interface: Layout
    
    Initializes fields in the node that may not have been set during the constructor. Must be called before the iterations begin.
