Draw an outline around each visual mass, each in the colour of its dot. At a minimum, use shape primitives such as ellipse or rectangle, but optionally other more complex geometries can be employed. Note that one of the ways to demonstrate knowledge of the services that are provided by the Graphics2D class is through the use of a variety of services and/or through the use of the more sophisticated and/or complicated services than the simpler services. A close fit around the visual mass is a desired feature.
The choice of silhouette image will clearly determine the complexity of the outlines.
