How can I make graphs if without any data available?

[Ledi]

I am interested in making some graphs to portray 4 different research
designs: Randomized experiment, regression discontinuity design,
instrumental variable design and matching on observables design. These are
all economic models. Basically, all I need is just conceptual graphs to make
it easier to understand the theory behind them. So, I don't have any data
available. Would anyone know how I could do that in excel. I appreciate
your time and help very much. Look forward to hearing from you.

Sincerely,

Ledi

Fake the data. Excel has to have numbers to work with. AFAIK there is
no way to "manually" create a chart.
