differential equations – Bifurcation Diagram plotting

I have simple diff. equation like $$frac{dx}{dt} = rx^2 – x$$. I need to plot the bifurcation diagram for this.

There are quite a lot of question regarding bifurcation diagram plotting and code given there but issue with me is that I am not able to understand the code. Can someone provide the code with explanation with what is happening in the code. I know commands like Plot, Manipulate, NDSolve,ParametricNDSolve,Table but when they include @,#,Row,Seap and other things it goes haywire for me.

Can anyone provide the code without those terms and explain a bit.
