In my professional and personal experience, react has never been better to use (in terms of features, DX, maturity, community, productivity), yet if you look at the "popularity" (oh dear) graph, it's basically just describing how older tech slides down while newer shiny tech comes in and is instantly the most "popular".
The "Back end frameworks" section is particularly bad. Sveltekit and Astro are not "back end frameworks" unless you define tech by what marketing copy people have written. Even express (which I still use daily for most of my back end projects) barely qualifies as a "framework" in my opinion. Again I have the feeling that choosing which techs go into this section is driven by something like "github star delta" rather than an evaluation of what the tech actually does.
Finally, jeez, angular isn't that bad. Plenty of enterprises use it successfully, and for companies with .NET or Java stacks, it's a great fit. I think almost certainly the devs at those kinds of companies are probably busy just doing their day job and not responding to "state of hype mixed in with some subtle marketing by commercial companies" surveys like this one has become.
