Using cytoscape.js to implement a distinct color mapping for node background colors

I am currently learning Javascript and Cytoscape.JS, and I am attempting to implement a discrete color mapping for my nodes based on a specific property in my data. This property consists of five unique values (a, b, c, d, e), and I want to assign colors to the nodes based on their respective groups.

My queries are:

  1. Can colors be automatically generated based on the number of unique values (in this case 5)?
  2. How can I assign these colors to all nodes?

I hope this explanation is clear. Lazloo

Answer №1

To come up with a unique approach, consider developing a function that can generate randomized colors and then establish an object map to retain these colors along with their respective values, for example: {a:'#red', b:'#blue'....}. Following this, assign a property such as bgColor within your node object utilizing the color map. In the styling of the node, simply set

'background-color': 'data (bgColor)'
.
