 _Force-directed graph layout using velocity Verlet integration._
 
-## Introduction 👀
-
-This module implements a [velocity Verlet](https://en.wikipedia.org/wiki/Verlet_integration) numerical integrator for simulating physical forces on particles. The simulation is simplified: it assumes a constant unit time step Δ*t* = 1 for each step, and a constant unit mass *m* = 1 for all particles. As a result, a force *F* acting on a particle is equivalent to a constant acceleration *a* over the time interval Δ*t*, and can be simulated simply by adding to the particle’s velocity, which is then added to the particle’s position.
-
-In the domain of information visualization, physical simulations are useful for studying [networks](https://observablehq.com/@d3/force-directed-graph/2) and [hierarchies](https://observablehq.com/@d3/force-directed-tree)!

-You can also simulate circles (disks) with collision, such as for [bubble charts](http://www.nytimes.com/interactive/2012/09/06/us/politics/convention-word-counts.html):

-
-You can even use it as a rudimentary physics engine, say to simulate cloth:

-
-To use this module, create a [simulation](#simulation) for an array of [nodes](#simulation_nodes), and compose the desired [forces](#simulation_force). Then [listen](#simulation_on) for tick events to render the nodes as they update in your preferred graphics system, such as Canvas or SVG.

-## Installing 🧑‍💻
-
-The fastest way to get started (and get help) with D3 is on [Observable](https://observablehq.com/)! D3 is available by default in notebooks as part of Observable’s standard library, and bundles d3-force. See https://observablehq.com/collection/@d3/d3-force
-
-If you use npm, `npm install d3-force`. You can also download the [latest release on GitHub](https://github.com/d3/d3-force/releases/latest). For vanilla HTML in modern browsers, import d3-force from Skypack:
-
-```html
-<script type="module">
-
-import {forceSimulation} from "https://cdn.skypack.dev/d3-force@3";
-
-const simulation = forceSimulation(nodes);
-
-</script>
-```
-
-For legacy environments, you can load d3-force’s UMD bundle from an npm-based CDN such as jsDelivr; a `d3` global is exported:
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/d3-dispatch@3"></script>
-<script src="https://cdn.jsdelivr.net/npm/d3-quadtree@3"></script>
-<script src="https://cdn.jsdelivr.net/npm/d3-timer@3"></script>
-<script src="https://cdn.jsdelivr.net/npm/d3-force@3"></script>
-<script>
-
-const simulation = d3.forceSimulation(nodes);
-
-</script>
-```
