I LOVE Rerun. But what is it?
Rerun describes itself as a tool to "infrastructure to ingest, store, analyze, and stream data at scale with built-in visual debugging. Fast, flexible, and easy to use." From my perspective, the "infrastructure" is a python API and a Visualizer GUI.
What makes rerun unique is that it puts sequence at the heart of everything. It prominently features a timeline that is so natural and essential for visualization in robotics!
