title: Plotting bar plot in Seaborn Python with rotated xlabels
body: <p>How can I plot a simple bar graph in Seaborn without any statistics? The data set is simply names and values.</p>
  
  <pre><code>import pandas
  df = pandas.DataFrame({"name": ["Bob Johnson", "Mary Cramer", "Joe Ellis"], "vals": [1,2,3]})
  </code></pre>
  
  <p>I would like to plot this as a bar graph with xlabels pulled from <code>name</code> column and y-axis values from <code>vals</code> and have x-axis labels rotated 45 degrees. How can it be done? Using <code>sns.barplot</code> like:</p>
  
  <pre><code>sns.barplot(x="name", y="vals", data=df)
  </code></pre>
  
  <p>will compute statistics that are not relevant here. </p>
