The basic rules of how to design a clear map are similar for tables, charts and other informational diagrams.
The above graphic shows 3 tables with the same text presented in different ways. I want to emphasise 'Carrot' under 'My Favourite Cakes' and for the table to be clear and easy to read. Which of the 3 best fits this need and list 4 reasons why?
The first table works the best because its format is subtle and simple. The rules it obeys:
A Large area should not be an intense colours (I used sludgy beige for background)
To 'flag' a small area an intense colour is good (the red of carrot)
Lines should be as thin as possible and single (gray is good)
The font should be clear without serifs (the sticky out bits), capitalise the first letter of the word but not the whole word.
Lines should not be doubled (as in the last two tables) as they create an optical effect. Thicken lines if necessary to make them stand out.
