change node based on users' input value

[sl yls]

I create a network graph via cytoscape.js. I am going to color the nodes in the network graph based users' input value (10 different values). e.g. (node1-1.5;node2:40,node3:2.5; node4:20;node5:2.3.........) Therefore, nodes will have different colors (from light color to deep color) in the graph. Users can judge whether nodes are important or not based on their node color. All ideas will be appreciated! Thanks.
