Problem with size nodes d3plus network

[Daniel Cano]

Hi, I need help with d3plus network.

I have the next code:

  var visualization = d3plus.viz()

   .container("#viz")    

    .data(sample_data)    

    .edges(links)

   .type("network")      

   .id("id")

    .depth(1)              

   .text("name")

   .tooltip("name")

   .size("size")        

    .color("tipo")        

   .draw()                

This code, when sample_data has little data nodes size is correct, but when I put in sample_data many nodes, the nodes sizes don't visualize correctly: the size nodes more bigger are visualized very little and vice-verse. 

Someone knows what happen? 

Thank you, for your help .
