1. The compatibility bar graph is pretty but tells me no new information and is just clutter. It will only ever be in 4 different positions and compatibility checkboxes are what's important. Furthermore, it makes it seem like compatibility across iOS, Android, Expo & Web is desirable when a library author might have good reason to leave one of those platforms out. (For example Android has no ARKit like library yet so a component that has binding to ARKit would only be '25%' compatible in your registry.)
2. You should highlight the fact that this is a project by Expo. Instead, you have you have to find that out by looking at your Github. Please be transparent that this is promoting the Expo platform.
