An appropiate graph visualization? I want to include a plot in my thesis to highlight regional differences in bicycle collision outcomes. Now there are several plot visualizations I could use, and I am not sure which one could be the most appropriate. Having a "scale free" y axis better highlights the differences between each region, but it may also confuse the reader.

I am aware that there might not be an optimal solution to this, but I would appreciate to hear your thoughts.(If you have a completely other suggestion for an appropriate plot than the ones below, I would also be happy to hear those).

These are the plots I have made:

Plot 1

Plot 2

Plot 3

Plot 4
It might be good to consider a broken y-axis. See this example. In your case, you only apply it to bicycle-only and bicycle-car.
