At the linked page you will see a section of the explanation titled Parametrization. This is the formulae for both x and y that you need to plot the curve in Grasshopper.

Either use Native components like the example below or use the Fx2 components and simply re-write the formulae into them.

You should note that the range of t is limited to -1 to 1 as if you go larger then you will introduce Complex numbers

Thank you, Danny! Finally I defined both formula in function modules.It's worked too. Cool!

You can use the polar equation.

You can also use the point polar component:
