plot.ly Hover Box Size attribute
<p>I'm using the <a href="https://plot.ly/python/reference/" rel="noreferrer">plot.ly Python api</a> and cannot figure out how to adjust the size of the plotly hover box size.</p>

<p>For example, in the visualization below the label for <em>CollegeClass....</em> is truncated. I would like to adjust the length of the string in the hover box.</p>
