I got tired of bubble charts I couldn't customize, so I built one where you can restyle everything (free, no login)

Bubble charts aren't new, cryptobubbles has been around forever and it's genuinely good. Two things always bugged me though: you can't change how it looks, and it only ever shows the whole market, never your coins.

So I built one into the tracker I work on. Bubbles sized by price change, market cap or volume, timeframes from 1H to 1Y, and you pick how many assets are on screen. There's a theme system if the default look isn't yours, and besides the market view you can load your own portfolio or watchlist as the bubbles, which is the part I actually use. Physics is d3-force, so they drift and collide for real instead of looping a canned animation.

I work on Mantapex, so read this with the appropriate suspicion. The market view is free and needs no account, that's what the link opens. Portfolio and watchlist modes do need one, since it has to know what you hold. And if all you want is a quick look at the whole market, cryptobubbles honestly does that fine too. Curious which theme people end up on. The default is called Big Blue but I keep switching to Asteroids.
