title: NetworkX node attribute drawing
body: <p>Im using networkx for visualization. I see when I use the function 
  draw_networkx_edge_labels 
  I can retrieve the labels for edges.</p>
  
  <p>I want to print the attribute on node ( instead of the label).. try everything almost . still stuck. If i have 5 attributes per node, is there anyway I can print a specific attribute on each node ? For example, if a car node has attributes: size, price, company, .. I want to print the size of the car on each node ? </p>
  
  <p>Don't know whether can output this on graph. </p>
