What determines the type of visualization to use?

I was considering making an AI agent to create visualizations and what seemed like what should be an obvious question is turning into a not so obvious thing. How do you determine what the optimum visualization to present analytics? At its distilled simplest, when do you pick a pie chart over a column chart? What determines that? As you add more visualizations, what are the decision points for choosing different visualizations. I'm not talking so much about decorations but how do you choose the best base visualization. submitted by /u/marketlurker [link] [comments]
