I have been making graphics (mostly flow graphs) for my presentations, lately, using Powerpoint and most recently LucidChart. I kind of avoided using Latex for this purpose as I had a feeling that its not going to be easy. Anyways, now I have decided to learn and master this powerful tool but going through the manual ,as I expected, is not a good idea for a jump start. So I was wondering if I can get some good advices that I should flow while making graphics in my beamer presentations. One thing that I have noticed that one needs to specify coordinates for everything. Is it a good idea to first draw a grid on slide and then proceed?
So please contribute practices that you have found to be useful for generating graphics using tikz package. I am looking forward to hear what experts have to say in this regard
