FLOW NFT Ecosystem - Market depth

Happy Flow NFT Day! As part of today’s celebration of FLOW NFTs, we want you to dive deep into the ecosystem. Treat this as an open analytics bounty specifically focusing on the FLOW ecosystem. Open Analytics (OA) bounties are bounties without specific prompts, just a direction, and a reward. It’s your chance to have your brain follow your heart — got a spark of interest, or a loose thread, or a weirdly-specific question gnawing at the back of your mind? Follow it as far as you can!
