If you find it useful, please support it by giving a ⭐️ on GitHub A custom Lovelace card that dynamically visualizes entities as a treemap. Rectangle sizes represent relative values while colors indicate status - perfect for comparing sensors, lights, thermostats, portfolios or any numeric data at a glance.
