title: Trouble reading and manipulating CSV file
body: <p>I am making a website which has to have interactive visualizations of data. So I am trying to make a visualization first and I am using Python with Bokeh. So we received some .csv files and they are pretty large.</p>
  
  <p>I already tried some stuff to visualize it but, I won't get it right.</p>
  
  <p>The .csv file looks like this, in short:</p>
  
  <pre><code>;A;B;C;DA;0;0;1;2;B;0;3;0;0;C;0;0;0;1;D;1;0;2;0
  </code></pre>
  
  <pre><code>df = pd.read_csv('coauth.csv', sep=';')
  df
  </code></pre>
  
  <p>Does someone know a way to get it into an array or how to manipulate it. Because when I try to read the file with the method above, I get a column as first column which is unnamed:0</p>
