I am taking an Economics class. We are required to plot and interpret 2D graphs. But often we have to use oddly shaped functions or have additional constraints we have to impose that make interpreting the graph tricky.
I am used to working with words and theorems to prove things. But my professor wants me to be able to articulate economic insights largely using visualization and let the graphs speak for themselves to some extent.
Are there any resources that can explain what kinds of information usually expressed using words can be communicated visually using graphs?
