> I was confused by the "concepts" sections—there's little meters with red and green, but it doesn't really express what those meters mean nor how they've been evaluated for each concept. It isn't explained, but if I'm not mistaken it looks like they put a green box in the meter for each different UI system that they've recorded for it. E.g. on https://open-ui.org/components/switch https://open-ui.org/components/switch, the "basic" switch has 5 green boxes in the meter: Ant Design, Atlaskit, Evergreen, Lightning Design System, Material Components Web. The next example, "autofocus" only has 1: Ant Design So it appears they are ranking the features (basic, autofocus, default, large, etc. of each component by how much support each feature has across design kits. I was confused too because using the green/red meter makes it seem like they're giving it a score or rating. A better alternative would to say: "We found 5 frameworks that support this feature"
