This will create and color a convex hull around the nodeset and return a reference to the convex hull object. To delete a specific convex hull you would type removeConvexHull(hull), and to get a list of all hulls you would use getConvexHulls().<br> + <br> + Note that convex hulls (especially transparent ones) make various operations a little slow so you may want to not use them until your are settled on a layout.<br> + <br> + To get the figure below we did:<br> + <br> + <br> + {{{clusts = groupBy(dept)<br> + for c in clusts: createConvexHull(c,randomColor(120))<br> + }}}<br> + <br> + <br> + The additional value we pass to randomColor indicates the transparency (0-255) for the resulting random color.
