Those two generate the coefficients that can be fed to [biquad~].
. A visual representation would be great.
The same coeffs that are fed to [biquad~] can be used to plot the frequency response (and phase response) with:

I don't deserve credit for them. They are based on abstractions created by Mike Moser-Booth.
Here is what the filterplot looks like:
