How to change marker size with pandas.plot()
<p>I have a chart created from <code>df.plot(style="o")</code> where the <code>o</code> markers are too big. Would it be possible to size them down?</p>

<pre><code>import pandas as pd
df = pd.DataFrame(range(1, 10))
df.plot(style="o")
</code></pre>

<p>How can I shrink them down?</p>
