I am new to D3 world and I built my first treemap.
I can't find solution to reserve the smallest node's dimension (certain width and height).
Basically, if you look at my JSfiddle, you will see that the smallest node having the size of 1 can't properly display its label inside because the box/node is to small so the text can't fit.
{"name": "label5", "size": 1}
Can someone please help how I can reserve/specify the smallest node's size (width and height) so the certain text/label could fit?
Here's my full JSFiddle:
