title: How would you replicate this graphic in R
body: <p>I'm wondering how to do this graph in R?</p>
  
  <p><img src="https://i.stack.imgur.com/xyhu0.png" alt="graph"></p>
  
  <p>I tought about using geom_bar from the ggplot package. However I don't know how to plot the changing thickness and the colors that reflect the growth for the years at the same time.</p>
  
  <p>I'd appreciate any ideas.</p>
  
  <p>Thank you.</p>
