### Converting to GIF

To convert your recording to an animated GIF, use Docker with the `agg` tool:
To convert your recording to an animated GIF, use the `agg` tool with podman:

```bash
cd output
docker run --rm -v "$PWD:/data" kayvan/agg /data/demo.json /data/demo.gif
# :Z flag required for SELinux contexts to allow container write access
podman run --rm -v "$PWD:/data:Z" docker.io/kayvan/agg /data/demo.json /data/demo.gif
```

Note: Using `podman` instead of `docker` avoids creating files owned by root.

This creates an optimized GIF suitable for embedding in documentation or sharing.
