This visualization demonstrates a shell script that installs Docker on Linux Mint by adding the Docker APT repository and installing the `docker.io`, `cgroup-lite`, and `apparmor` packages. The script checks for HTTPS transport support via `/usr/lib/apt/methods/https`, installs `apt-transport-https` if missing, and uses `apt-key adv` to import the repository key. It also adds the current user to the `docker` group with `usermod`. The code uses standard bash commands and APT APIs, with an optional fallback to the curl-able installer at get.docker.com.
