ambientAlphaTarget

By default a d3-force simulation "cools down": its internal energy (alpha) decays toward zero and the graph comes to rest. ambientAlphaTarget sets a floor under that decay, so the simulation keeps gently running forever — nodes drift and sway as if floating in water.

<Graph
  graph={data}
  ambientAlphaTarget={0.05}
/>

Value	Behavior
0 (default)	Standard d3 behavior — the graph animates into place, then settles.
0.02 – 0.05	Subtle, organic drift. The sweet spot for most uses.
0.05 – 0.1	Lively, noticeable motion.
> 0.1	Chaotic — the layout never really stabilizes.

Slide it to 0 and watch the graph freeze; nudge it up and it comes back to life:

ambientAlphaTarget={value} — 0 settles, higher floatsLive

When to use it

• Landing pages and dashboards — a slowly breathing graph reads as "live data" and draws the eye (the hero on this site uses 0.04).
• Frequently-changing graphs — a warm simulation absorbs node additions and removals more gracefully than a cold one.

Mind the CPU

A non-zero value means the simulation ticks — and your nodes re-render — on every animation frame, indefinitely. Keep NodeComponent cheap, and prefer 0 for very large graphs or battery-sensitive contexts.

The prop is fully reactive: change it at runtime (e.g. pause motion when a tab is hidden) and the simulation adjusts immediately.
