title: Produce a random Voronoi diagram with a specific length and width?
body: <p>A Voronoi diagram is an approach to the tessellation of medium.</p>
  <p>In this diagram, there are many points in a plane that divide the medium to many specific regions by their bisector. Any region is convex and has a circumscribed rectangle.</p>
  <p>The circumscribed rectangle of convex shape that has the smallest area (We have an algorithm to imagine any edge on the direction of a specific edge and perpendicular to edge and find a rectangle with the smallest area.).</p>
  <p>I want to place the points in a way that creat random convex polygons (Random means have different numbers of edges.).</p>
  <p>But I want to control the size of the width and length of their circumscribed rectangle.</p>
  <p>So I want to know is there any algorithm for the locating points with the above property?</p>
