You can use the visualcounter module, the documentation is included in the 
package
or you download it from the github [1] page.

[1] https://github.com/adityam/visualcounter 



Complete example attached. You can easily make the fill color and draw 
color to be configurable by a key-value interface.


The counter corresponding to itemgroups is called 
\v_strc_itemgroups_counter.

mp=visualcounter::randomcircle,
rulethickness=1pt,
  ]

\startuseMPgraphic{visualcounter::randomcircle}
  begingroup;

  \includeMPgraphic{visualcounter::initialization}

  if (last_counter > 0) and (current_counter > 0) :
newpicture countertext ; countertext := textext("\visualcounterparameter\c!text");
newpicture max_countertext ; max_countertext := textext("\visualcounterparameter{\c!max\c!text}");

newnumeric diameter;
diameter := 1.75 * max(bbwidth(max_countertext), bbheight(max_countertext)); 

newpath randomcircle; 
randomcircle := fullcircle xyscaled(diameter, diameter) randomized (diameter/20);

pickup pencircle scaled \visualcounterparameter\c!rulethickness ;
fill randomcircle withcolor green; % Can be made configurable
draw randomcircle withcolor blue;  % Can be made configurable

label (countertext, origin);

Indeed as also used in the simpleslides module.

The puzzler is for you to understand why I only increment by 1/2 ;-)
Perhaps someone else can suggest a better solution?
