title: TensorBoard Embedding Example?
body: <p>I'm looking for a tensorboard embedding example, with iris data for example like the embedding projector <a href="http://projector.tensorflow.org/" rel="noreferrer">http://projector.tensorflow.org/</a></p>
  
  <p>But unfortunately i couldn't find one. Just a little bit information about how to do it in <a href="https://www.tensorflow.org/how_tos/embedding_viz/" rel="noreferrer">https://www.tensorflow.org/how_tos/embedding_viz/</a></p>
  
  <p>Does someone knows a basic tutorial for this functionality?</p>
  
  <p>Basics:</p>
  
  <p>1) Setup a 2D tensor variable(s) that holds your embedding(s).</p>
  
  <pre><code>embedding_var = tf.Variable(....)
  </code></pre>
  
  <p>2) Periodically save your embeddings in a LOG_DIR.</p>
  
  <p>3) Associate metadata with your embedding.</p>
