title: How to make a pie chart smaller with matplotlib
body: <p>I have my pie chart, and would like to make the circle smaller. 
  On current size, I can not read one of the labels. (imported matplotlib as <code>plt</code>)</p>
  
  <pre><code>title('Distribuicao recomendada de calorias por refeicao', bbox={'facecolor':'0.8', 'pad':3})
  labels = 'Cafe', 'Lanche1', 'Almoco', 'Lanche2', 'Janta', 'Ceia'
  sizes = [20, 5, 30, 15, 20, 10]
  colors = ['yellowgreen', 'gold', 'lightskyblue', 'lightcoral', 'blue', 'pink']
  explode = (0.05, 0.1, 0.05, 0.1, 0.05, 0.1) #serapação das rfeições
  plt.pie(sizes, explode=explode, labels=labels, colors=colors,
          autopct='%1.1f%%', shadow=True, startangle=90)
  plt.axis('equal') #transforma em círculo
  
  plt.show()
  </code></pre>
