How would this work in a chat environment? My perspective is that I could view all of the emojis I have reacted with toward any other user's posts. It's tough to say how to adjust the other emojis. I would want to create my own graph and adjust it over time. Perhaps the other emojis could be addressable by the user as desired?

The way I select an emoji now on Amethyst for instance, I am given some defaults and can add my own emoji. So I would expect a graph to work the same way.

"Here is all of your emoji reactions you have submitted on Vitor's notes/events that fit within the predetermined 74 emojis provided by Amethyst"

Then I click the filter and select an external emoji; it looks for it, and allows me to plot it in accordance with the valence-arousal axes.

It would be even more interesting if this were public data. For instance if I were to sign in with your npub, it would be amazing to see how you sort your emojis into your own emotional narrative, and how that reflects across your public events. I assume this is possible.

This is how I believe "Web of Trust" will be represented on Nostr, personally. I prefer to think of it as Web of Emotion or Web of Reactions. I think it is freely obtainable data that gives us a more complete emotional narrative. It might help one form a loose narrative of trust (between decentralized and often anonymous users).

The third dimension is like a heat map. If I react to Vitor with 100 👻 emojis, it must be heavily represented on the chart. I am not familiar enough with tridimensional dataset visualization to imagine it further. Would love to play with NIP-25 datasets soon.
