Make a graph with circles bigger than radius:5

[corganfuzz]

How do I make a Graph with circles bigger than 5 px ( or whatever the unit is)?
If I do radius: 50 , the links do not scale along with the new radius. so how do you change the links length, size ?

<ForceGraphNode
                  key={id}
                  node={{
                    id,
                    label,
                    // radius:50
                  }}
                  fill={data.nodes.type}

I have the same question, how can you configure the length of links between nodes?

I found that adding a radiusMargin in simulationOptions lets you account for a larger node radius and makes the lines longer

<InteractiveForceGraph
        simulationOptions = {{
          height: 900,
          width: 1680,
          radiusMargin: 20 //3 is default
        }}
