points plotted at same coordinates overlap

## Use Case

When plotting data with discrete-valued features, it is frequently possible to have many images stacked up on the same coordinates.
It's impossible to disambiguate or get to all the images in this way.

## Solution

Some way to explode or jitter the stack of points to allow them to each be hovered over individually. I did some experimentation with plotly.js but it seems there is no good way to do this that still scales to the size of our datasets. It would be great to find a built-in plotly feature to make this happen.
