sorry if this is a stupid question.. still getting use to nodebox3. I have a set of points (i'll call them hubs) - i joined them with lines. Then i thought while out walking, Each line is 2 points so there is a point for every connecting line at eachhub. I wanted to add an elipse at each hub and scale it based on the number of points at that hub. how would i go about counting the number of duplicate instances?
I got as far as adding a distinct node, so i have the number of unique points.

to make this a bit clearer, If i had a list : [1,1,2,3,3,3,4,7,9,4,3,2,6] or similar how could i get a list of unique values with a count
like [1-2, 2-2, 3-4, 4-2,7-1,9-1,6-1]

hope this isn't a annoying question. Congrats on the excellent piece of software
