How to implement on d3 force directed graph

Thank you for the very interesting library. 

I would like to implement it with a d3 force directed graph, where on every tick the current position of the nodes and links must be updated. https://observablehq.com/@ms007/fruits

Do I have to change the data and call render on every tick?
And must the nodes and links each have its own render function?

Thanks for your assistance
