Yes already tried a little bit, but i dont understand what to put where.
Have already finished a project mapping all my patients on a regional map including changes over time includin an extra program for data mining an prprocessing.
Thus i have some minimal basic knowledge
I tried to reuse the both treemap examples in the book:

class WertItem extends SimpleMapItem {
 String kostenart;
 String abteilung;
 float wert;
 WertItem(String kostenart,String abteilung,float wert) {
   this.kostenart =kostenart;
   this.abteilung = abteilung;
   this.wert = wert;
   }
   
    void draw() {
   fill (255);
   rect(x,y,w,h);
   
   fill(0);
   if (w >textWidth(kostenart) +6) {
     if (h >textAscent() +6) {
       textAlign(CENTER,CENTER);
       text(kostenart,x+w/2,y+h/2);
     }
   }
 }
wert is the value to be calculated
As I understand the first example an array of values have to be created.
Dont know if this is right, and how to create the SimpleMapModel
