title: Python show image upon hovering over a point
body: <p>I have a 2-d scatter plot of points, that correspond to images. I was wondering if there's an easy way to display the corresponding image (as a popup or tooltip) when you hover your mouse over each point? I tried plotly but found out you need to manually edit javascript to get the hover event to work. Is there a simple solution just with matplotlib or some other common package?</p>
