I think you want to find group names that exist in one list but not two lists.

So here is my solution:

As pointed by Aleks Andreev in the comment

Try cut spaces from lastName like OrderBy(s => s.LastName.Trim())

Here's an approach using ggforce::geom_circle to get precise control over the circle placement. The challenge I run into is that the original data has numeric height of 100+, but numeric width of only 2 (2015 to 2017), but ggforce::geom_circle creates a circle that will be proportional to the coordinates. So if we leave x and y as-is, you'll get a very tall and narrow chart, or else you'll get very squished circles. My hack is to scale the values from the start. (And I use their square root so that the values are scaled to the areas and not the radii.)

I wasn't sure if the y values would be used in the final chart. If you can drop them, then this should suffice, but if you need them then you could either manually change the labels on the y breaks or use a labeller to get them to display with the original scale.
