Show HN: Browser-Based Map Animations

Hi HN

I’ve been working on Super Map World, a creative mapping platform and just launched a new animation feature.

Try it: https://supermap.world/tools/map-animation

What it does: The feature lets you animate maps directly in your browser with a few clicks. You can animate routes, regions, or just simply see a globe in your chosen style rotate from point to point. It’s designed for people who want to make short visuals e.g. social clips, or storytelling maps without needing to figure out GIS tools.

Under the hood: Everything runs client-side. I'm using d3.js to render the map on each frame for FFmpeg.wasm to compile to video. No background tasks or uploads means my cheap server instance doesn't have to do much.

Would love feedback on:

- Performance (especially on slower machines) - What kinds of animations you think would be cool

Thanks for checking it out.
