Trying to use package/@grafana/ui in React Project

I am trying to integrate this package to build something like this → Grafana
Can someone help me integrate this? or suggest workarounds ?

isn’t grafana/ui just a package containing components developed by the Grafana team to use them in custom plugins ?

Like @kasmir says @grafana/ui is designed to be used for Grafana itself and plugin development. It’s not intended to be used as a standalone design system. I suggest that you instead look along the lines of Material UI and Ant Design, but there are many other alternatives.
