title: TypeError: scatter() missing 1 required positional argument: 'data_frame' in Plotly
body: <p>I am a noob and was using the first example of Plotly Scatter plots.</p>
  <pre><code>import plotly.express as px
  fig = px.scatter(x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])
  fig.show()
  </code></pre>
  <p><strong>Error I got</strong></p>
  <p>TypeError: scatter() missing 1 required positional argument: 'data_frame'.</p>
  <p><strong>What I tried</strong></p>
  <pre><code>fig = px.scatter(data_frame=None,x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])
  </code></pre>
  <p>This does not solves my problem.
  Kindly help</p>
  <p>Thank You</p>
