There was once upon a time many of us bumped into this issue. Unless you are gifted or happened to take up a design course before, it could be quite challenging and time-consuming to produce visually aesthetic charts that are intuitive to the audiences at the same time.
Here is what crosses my mind back then: I want to be more intentional in crafting my charts such that it conveys information to my audience intuitively. By that, I mean not expending their brainpower and consuming their time excessively just to make sense of what is happening.
