Soft question: How do you create/draw/plot economic graphs digitally? Obviously I'm talking about a theoretical graph not one where you can just plot the data. The only two options I can think of are just using shapes in word/powerpoint or using TikZ in Latex which is very time consuming.
I would be interested to know what your preferred methods are for drawing good looking digital graphs.
Give @Giskards comments I'll put up my answer in the comments as answer. I usually fake the data and then use my favourite plotting program. For example here is the requested income substitution graph challenge created with R and GGplot2. For completeness I add the code, but given that it's quite long I add it to the end of my answer. Added bonus of GGplot/R is that if one is well versed with it it is simple to include LaTEX annotation.

Making a similar graph in Excel is also doable. I'll admit though that Excel becomes a pain once we want multiple axes and scales, and the same probably applies to GGPlot. And of course Excel doesn't work well with LaTEX.
Code to generate graph (all parameters can be adjusted, the only thing that needs to be fixed afterwards is the vertical position of the arrows and the text).

#As the A in that function is just for scaling we'll set it to 1
