title: Draw rectangles with different scales in R
body: <p>I want to draw two rectangles that are connected by a series of lines. However, the size of the top rectangle is 157 while the bottom one is 75. </p>
  
  <p>I don't want the bottom one appears smaller but to draw them with different scales as shown in the graph. </p>
