Hi there, 
  
   I would like to know, is it possible to have a Drag Node Chart with check boxes in a legend that can show/hide certain classes of elements, such as links between nodes, node labels, and link labels? The functionality I'm imagining would be similar to the Power / Temperature / Speed toggles in the multi-axis line chart here: http://www.fusioncharts.com/charts/multiaxis-line-charts/ 
  
Thanks in advance, 
Daniel
