Thank you martin
In fact it is a viszualisation for a very simple request
eg. all the customer buing a product
The object should accept as parameter the name of the 'product'
and using the in memory data module and another parameter as 'customer'
then display in the central buble the name of the product and all around it in different bubles all the the different customers name that bought it
easy requirment but hard to make (or not)
